The dog's hind legs are failing: causes of pathology, how to treat the disease. Weakness of the dog's hind legs. Why? What to do

One of the frequent complaints of owners of dogs with neurological problems is that both hind legs fail. In this case the dog:

• Starts to move abnormally.
• The hind legs seem to stop obeying and become weak.
• Paresis or complete paralysis develops pelvic limbs.

Most often, this problem occurs in dogs of small and medium breeds that have a genetic predisposition to lesions of the intervertebral discs. These dogs include mainly dachshunds, in addition to all brachycephalic breeds - Pekingese, French bulldog, Brabançon and others. Typically, these dogs' hind legs begin to work abnormally between the ages of 3 and 8 years.

The first symptom of neurological disorders in the thoracolumbar region spinal column, which lead to the dog beginning to lose its hind legs, is pain. Later, weakness appears, the inability to move the limbs, and last of all, pain sensitivity disappears.

These symptoms usually come on suddenly while walking or playing with other dogs, or without visible external reasons in a state of relative rest. Sudden movements can trigger the appearance of such symptoms, but are not their main cause. Many dachshund owners believe that the significant length of the spinal column plays a role in the development of the disease, but this is not true. Sometimes the manifestations of the disease occur all at once, but it also happens that in the morning the dog feels only pain, and by the evening paralysis of the limbs develops with loss of pain sensitivity.

There can be many reasons why dogs' back legs fail. And, of course, those owners who suddenly encountered this problem are lost and don’t know what to do. Just yesterday their pet was briskly jumping on the sofas and playing tag with the neighbor's dogs, but today it lies indifferently, unable to get up.

Cases of damage directly to the extremities include injuries (fractures, sprains and ruptures of tendons, damage to peripheral nerves), as well as arthritis and arthrosis of the joints of the extremities, tumors.

If the above diagnoses are excluded, then we are most likely talking about spinal pathology, that is, a violation of the innervation of the limbs due to any pathological influences on the spinal cord. Paresis and paralysis hind limbs develop in case of damage spinal cord at the level of the thoracic and (or) lumbar spine.

• Injuries

Refusal hind legs in a dog it can occur as a result of trauma - with fractures, sprains and ruptures of ligaments and tendons, with damage to peripheral nerves, as well as due to diseases such as arthrosis, arthritis of the joints of the limbs, tumors, discopathy and herniated disc. In addition to these diseases, spinal pathology is possible, in which the innervation of the limbs is disrupted due to the impact of adverse factors on the spinal cord. Paresis and paralysis are frequent accompaniments of spinal cord lesions in the lumbar and thoracic regions.

A common reason why the back legs of dogs fail is of a traumatic nature: car injuries, falls, blows, severe bites during fights. In some cases, such consequences may result from unsuccessful flip flop, jumping and slipping on the ice crust.

At the site of direct injury to the spine, the integrity of the spinal column (its structure) is disrupted, swelling occurs, which leads to compression of the spinal cord and radicular nerves. Accordingly, the supply of blood with oxygen stops, and with prolonged compression nerve cells die, which makes it impossible for nerve impulses to pass through peripheral nerves. Strong traumatic injury leads to disruption of the integrity of the spinal tissue, and rupture of the spinal cord occurs.

• Degenerative diseases of the spine

Refusal normal functioning hind limbs in dogs can provoke degenerative diseases of the spine, which are characterized by disruption of important metabolic processes in its tissues. So this leads to pathological changes structures of the spinal column.

• Spondylosis

A dog’s hind legs may fail due to spondylosis – “local aging” of some vertebral segments. This disease progresses very slowly and is practically undetectable at the earliest stage. First of all, the outer fibers of the fibrous ring are affected (the consistency of the nucleus pulposus is preserved), and then calcification of the anterior longitudinal ligament begins. Osteophytes develop, which visually resemble beak-like growths.

• Tumors in the spine

Tumor-like processes gradually developing in the immediate vicinity (or itself) of the spinal cord lead to pathological changes and fractures of the spinal column. With a sharp exacerbation of the process, swelling and compression of the roots and spinal cord occurs, and the dog can be observed the following symptoms: weakening or failure of the hind limbs, arched back, gait disturbance, when the body position changes, the dog yelps, associated disorders occur (impaired urination and defecation), in some cases, refusal to feed.

• Spondyloarthrosis

The consequence of static loads in osteochondrosis of the spine can be spondyloarthrosis (deforming arthrosis of the joints of the spine). Uneven loads on the spinal column can also lead to protrusion of the nucleus pulposus of the intervertebral disc through the pathologically altered fibrous ring. This phenomenon is called a vertebral hernia. Protruding towards the spinal cord, the hernia causes compression of the radicular nerves and (or) the spinal cord.

• Discopathy

Neurological lesions of the pelvic limbs are most often based on diseases of the intervertebral discs (discopathies). In this case, the altered disc substance penetrates the spinal canal and pinches the spinal cord or spinal nerve roots, which manifests itself in the form of a neurological deficit. Often large dog the hind legs fail, and this problem has its own characteristics. Similar lesions are observed in older animals of large and giant breeds: German shepherds, Dobermans, Rottweilers, Great Danes and others. As a rule, this group of dogs develops clinical symptoms progresses slowly over several months or even years. In this case, we can assume lesions of the intervertebral discs in the lumbar spine or at the level of the lumbosacral junction, as well as lumbosacral stenosis.

Discopathy is very common in dogs - French bulldogs. This is due to anatomical structure an animal when, as a result of artificial selection, the spine has become elongated, and now undergoes stronger loads than the spine of “normal” dogs. The distance between the vertebrae has become significantly greater than normal. This is due to genetics and is inherited. Disc prolapse can occur not only during active movements and jumping, but even at rest, when the dog is sleeping or lying quietly.

• Dysplasia

Very often, owners of dogs of heavy breeds (St. Bernard, shepherd dogs, Labrador retrievers, Great Danes, etc.) encounter diseases of the musculoskeletal system. The most common disease in puppies is dysplasia. hip joints. This disease is hereditary and appears most often between the ages of 4 and 10 months during intensive growth. First there is a problem when getting up, especially after sleep. The dog limps, then straightens up and walks normally. Further without treatment, the symptoms may intensify, until the dog completely refuses to walk. If you notice such signs, you need to take your dog to the vet and get an x-ray.

• Osteocondritis of the spine

Spinal osteochondrosis is considered the most severe form of damage; this disease is based on degenerative processes in the intervertebral discs (discopathy), often involving the surrounding vertebral bodies, as well as changes in the ligamentous apparatus and intervertebral joints.

The reasons for the development of osteochondrosis can be:

• Genetically determined developmental defects causing vertebral instability.
• Rheumatoid lesions.
• Spinal injuries.
• Impaired microcirculation leading to disruption of disk nutrition.
• Autoimmune processes.

Spinal pathology is also possible, which arises from the influence of adverse factors on the spinal cord. Frequent companions of spinal cord lesions in the thoracic and lumbar region are paresis and paralysis. Most often, dogs' paws suffer from falls (especially in small breeds), car injuries, blows and severe bites during fights.

Even an unsuccessful jump, a sharp turn, or a dog slipping on an icy crust can lead to paw failure. At this moment, at the site of spinal injury, the integrity of the structure of the spinal column is disrupted, swelling occurs, which compresses the radicular nerves and the spinal cord.

Of course, the answer will be to contact a veterinarian, preferably specializing in neurology. If you notice a painful reaction in your dog when changing body position, a tense gait, a reluctance to walk, especially on stairs, do not wait until its hind legs give out - immediately show the animal to a doctor, then the treatment will be more effective. If the problem with your hind legs has already happened, you shouldn’t wait any longer.

If the animal has suffered a spinal injury, try to get it to the doctor as quickly as possible and in an immobilized state (secure the animal on a board using bandages or straps). Do not use painkillers until you see a doctor. Pain limits the animal's activity, which helps avoid further displacement of the vertebrae during a fracture.

It is possible to notice the onset of the disease and urgently consult a specialist, but most inexperienced owners don't give any importance to such important symptoms How:

• Anxiety.
• The dog hides and squeals when someone touches its back.
• The dog is passive when other dogs are frolicking.

However, in most cases, the alarm begins to sound when the dog’s hind legs partially begin to fail, or paralysis develops. And here it is necessary to differentiate such a disease as radiculitis. An incorrectly prescribed treatment (for example, massage instead of maximum immobilization of the animal) will waste valuable time and aggravate the situation.

The sooner help is provided to the dog, the better the prognosis for its recovery. In any case, you shouldn’t despair, because there are known cases when completely immobilized dogs were put on their paws and returned to active life. Depending on the diagnosis, it is prescribed drug treatment in the form of injections. A more radical case in the case of spinal diseases is surgery, after which treatment also continues.

In parallel, the dog is prescribed a massage; during the recovery period, swimming is recommended, and exercises with the dog after it returns to physical activity. All dog owners should remember that it will not be possible to help a paralyzed dog at home. You must definitely see a doctor, undergo all the prescribed examinations to make an accurate diagnosis and start timely treatment.

First, the doctor will conduct an examination and evaluate general state, will provide emergency assistance and make a primary diagnosis. If we are talking about spinal pathology, the doctor:

• Check the preservation of sensitivity (tactile and pain) of the limbs.
• Checks the integrity of the reflexes.
• Check for pain in the spine.
• Will appoint X-ray examination.
• Myelography may be performed, that is, X-ray will be done after introducing a special X-ray contrast agent into the spinal canal. This is done to identify the slightest violation, not noticeable on regular photo, as well as to determine the exact localization of the process. If necessary, he will prescribe blood and urine tests to identify concomitant pathologies (pyelonephritis, kidney, liver, heart failure, etc.).

The conducted studies will help the doctor assess the extent of the lesion, give a prognosis of the disease and make a decision on treatment. Perhaps the doctor will give you a choice between surgical and therapeutic methods of treatment, perhaps he will insist on one of them.

Often in veterinary clinic Owners contact us, complaining that the dog’s hind legs are being lost. Each of them describes the symptoms in their own way: the pet is limping, has a hunched back, drags its paws, and has paralysis.

Introduction

There is no single reason that can cause such symptoms. Dog veterinary evidence suggests that the first step in treatment should be qualified diagnosis. To know how to treat, you need to know what to treat. And you can’t do this without a trip to the veterinarian.

Individual pathologies when a dog loses its hind legs include age and breed predisposition. Thus, pugs, poodles, English and dachshunds and Pekingese have a predisposition to the destruction or displacement of intervertebral

Discopathy

This pathology is quite serious and can be life-threatening pet. As the disc shifts, it compresses. Outwardly, this will manifest itself in periodic attacks. severe pain: the pet freezes in one position (usually with a hunched back and with an outstretched neck), shortness of breath appears, severe trembling, the hind legs weaken and give way.

Scientists have not yet fully identified the reasons why the strength of the intervertebral disc decreases in dachshunds. Installed genetic predisposition in some dog breeding lines. Due to the mutual pressure of the vertebrae on each other, the nucleus pulposus moves into the thickness of the fibrous ring and subsequently leaves its limits, entering the paravertebral space. The fibrous ring on the side of the passing spinal canal has the least strength, and therefore parts of the destroyed disc are usually displaced in this direction. This causes compression of the spinal cord overlying it, as well as its nerves.

If the compression of the spinal cord is not so clearly expressed, then clinically it will only manifest itself in this way - the dog’s hind legs have failed. The pet drags them along, trying to transfer the weight of the body to the forelimbs. He tries to jump onto a chair (sofa, armchair), but he can’t. Can't bend over to the floor or bowl. If there is a suspicion of discopathy, you need to go for a qualified diagnosis and prepare for treatment, up to surgical intervention. Compression of the spinal cord can cause irreversible changes in the body when therapeutic measures will simply be ineffective.

Dysplasia

In pets giant and large breeds(Labrador, Newfoundland, Rottweiler, Great Dane, St. Bernard, german shepherds 4-12 months of age) also have their own predispositions to the disease when the dog’s hind legs fail. This lesion The occurrence of this pathology can be influenced by many things: heredity, overweight puppy, unbalanced diet, etc.

Causes of dysplasia

There have been many scientific debates regarding the causation of this disease. And so far, two theories have been formed about the heredity of this pathology and the mechanism of inheritance.

Many geneticists advocate the theory of additive inheritance. That is, the disease develops due to the action of genes that are involved in the final formation of the hip joint.

The second theory is based on the assumption that these same genes influence each other, and their interaction is combined in various ways. This means that the defect has a much more complex hereditary nature than is shown by the first theory.

There is a third theory in the world of geneticists. It combines the first two. According to it, the action of the genes responsible for the creation of joints can be summed up, and individual genetic pairs influence each other in different ways.

The general conclusion of experts: the disease is classic example a quantitative trait influenced by many genes (polygeny), and in this case many factors environment have their impact on the final formation and manifestation of symptoms. Clinical manifestation dysplasia, when a dog loses its hind legs, does not occur in all animals. But this does not mean that a pet at risk is not susceptible to this pathology, if not severe symptoms. When choosing a partner for mating, you should study the pedigree for the presence of ancestors with dysplasia. It should be noted that the disease can be transmitted to descendants through fourteen generations.

Swedish dog veterinary medicine has clearly proven that dysplasia is associated with heredity and is inherent in certain breeds. And if the breed is characterized by a powerful physique and large mass, then the likelihood of disease is very high. The dog carries a huge load. It gives the body a pushing force from the hind limbs when moving. And during this push, the joint extends and moves the head of the femur along the entire acetabulum. Particularly high friction occurs in the joint when the animal, standing on its hind legs, jumps or walks.

If the hip joints are affected, then weakness hind legs will appear immediately after a period of rest (when getting up in the morning) and decrease with physical activity. Also, this lesion is rarely symmetrical; the dog will begin to “fall” on only one paw.

Myositis

In middle-aged dogs after too large physical activity the next day, muscle inflammation may develop - myositis. Due to overvoltage, tearing, rupture, and fiber disintegration may occur. muscle fibers and hemorrhage into the thickness of the muscles. Due to damage, traumatic swelling develops, and with significant rupture of muscle fibers, a scar forms and the muscle shortens. This leads to myogenic contracture of the corresponding joint. If the affected muscle gets pathogenic microflora- purulent myositis will develop.

One of the symptoms of this disease will be a “stilted gait” or weakness of the hind limbs; the dog will limp on its hind leg. Treatment of dogs with such a disease will not cause great difficulties, but only

Osteochondrosis

Another disease that can cause your pet to have problems with its hind legs. The main reason is a violation of cartilage mineralization. Typical for large breed puppies. Osteochondrosis is a multifactorial disease. Nutrition and genetics play key roles. Cartilage separation in this pathology is most often observed in the joints subject to the greatest load (hip). The result will be lameness, the dog will be limping on its hind leg.

Fractures

This pathology is often found among large breed puppies. And many owners consider injury to be the cause. The dog presses his back paw and cannot lean on it. Reacts painfully to touch. In most cases, a fracture occurs with minimal external impact. This type of injury is called a pathological fracture and indicates low mineralization of the skeleton. Causes: low intake of calcium or vitamin D, high intake of phosphorus.

For recovery in this case, it is not enough to fix the fracture. The main thing is to appoint proper diet. The best option- use ready-made feed, balanced in the content of phosphorus, calcium, vitamins D and A. An excess of these substances will delay bone healing.

Old age

Older dog falling on his hind legs? This may be due to a malfunction of the brain. According to the observations of veterinarians, this most often happens due to various vascular problems, less often - the reason is the presence of brain tumors. Competent treatment in this case, it can significantly improve the pet’s well-being and extend its life for years.

What should be distinguished from

Kidney problems cannot be the reason why a dog loses its hind legs and has a hunched body unless the pet is extremely malnourished with autointoxication. But in this case, the weakness will spread to the entire muscular system.

What not to do

The most common mistake owners make when identifying hind limb weakness is self-treatment dogs with non-steroidal anti-inflammatory drugs (diclofenac, indomethacin, aspirin, etc.). The clinical improvements observed by the owners after the use of these drugs are only temporary, but they well hide the underlying disease, which makes it very difficult correct diagnosis a disease that causes the loss of a dog's hind legs. Also, medical anti-inflammatory drugs carry a number of serious side effects for pets, including ulcers on the walls of the stomach and bleeding in it.

Many dogs are susceptible to developing musculoskeletal diseases. Cases when their hind legs fail are not uncommon. There are several reasons for this condition.

Which breeds are most likely to have hind leg failure?

This problem is usually faced by owners of small and medium-sized dogs.

Dachshunds have a predisposition to lesions in their hind legs.

Some breeds have a genetic predisposition to intervertebral disc disease. Specific symptoms observed in:

1. Tax.
2. Brabançonov.
3. French bulldogs.
4. Pekingese.

Impairment of the hind limbs is observed at approximately 3–8 years of pet's life .

Main causes of pathology

This symptom is often observed against the background of impaired innervation of the paws.. The provocateur may be a lesion of the spinal cord at the lumbar or thoracic spine.

The development of arthritis can cause the hind legs to fail.

But the hind legs can also fail due to development:

Discopathy is often observed in Basset dogs.

Features of dysplasia

This pathology is very difficult to treat.

Dysplasia often occurs in Great Dane dogs.

Often dysplasia passed on to dogs genetically . Therefore, when purchasing an animal, you need to ask for both documents and tests for this disease from its father and mother.

Features of osteochondrosis

Osteochondrosis in a dog in the picture.

A conditional “continuation” of discopathy is osteochondrosis.

The main reason for this serious illness considered to be impaired mineralization of cartilage. It quickly hardens, which helps.

Osteochondrosis dangerous because if left untreated, the animal’s hind limbs gradually fail.

Features of arthritis and arthrosis

Arthritis and arthrosis occur more often in older dogs.

These pathologies are most often diagnosed in dogs of heavy, large breeds. The main difference between arthrosis and arthritis is the absence of inflammation. There is a rapid change in the cartilage, which soon collapses. With arthritis, the joint capsule becomes inflamed. This disease occurs in older animals.

Symptoms

The first specific sign is pain syndrome. A little later, the dog becomes weak and lethargic. She has difficulty moving her paws. Pain sensitivity disappears last.

Pain in the limbs is main symptom diseases.

These signs may appear while playing with other animals.

1. If the disease is advanced, symptoms appear even when the dog is in a state of relative rest.
2. Sometimes all the signs of the disease appear immediately . Often in the first half of the day a pain syndrome occurs, and in the late afternoon paralysis of the paws develops.
3. Most insidious disease is spondylosis . At first it proceeds slowly and is not detected on early stages. As the pathology progresses, the development of osteophytes is observed. Visually, they resemble beak-like growths.
4. Tumors in the spine also do not manifest themselves at first . When the process worsens, the spinal cord is compressed. This leads to arching of the animal's back and disruption of its gait.
5. When getting up and sitting down, the pet may yelp in pain . Involuntary urination is sometimes observed. In some animals, the act of defecation is disrupted. A weakened dog may refuse to eat.

How can you help your dog?

Having found at least one of the following in a dog alarming symptoms, need to contact your veterinarian as soon as possible, specializing in neuroscience. To establish a primary diagnosis, the doctor:

1. Orders an x-ray examination.
2. Checks for pain in the spine area.
3. Clarifies the safety of reflexes.
4. Checks for pain and tactile sensitivity.

If you notice any alarming symptoms, you should immediately consult a doctor.

Sometimes a sick animal is prescribed a myelogram. The conducted studies help the veterinarian assess the stage of the lesion and decide on therapeutic tactics.

When diagnosing, it is very important to differentiate radiculitis. Erroneous treatment contributes to the worsening of symptoms.

Drug treatment

If the dog’s condition is characterized as acute, it is prescribed the use of steroid hormones:

1. Solumedrol.
2. Metipreda.
3. Dexamethasone.
4. Prednisone.

Solumedrol is used in acute cases of the disease.

At the end of this course, the dog is prescribed non-steroidal anti-inflammatory drugs. medicines. The pet is recommended to take Rimadila, Quadrisola .

“Human” NSAIDs should not be given to animals.

This leads to an opening stomach bleeding. Death often occurs.

In order to improve the nutrition of nervous tissue, the dog is prescribed B vitamin injections . The metabolism of oxygen and glucose in affected tissues is activated by Actovegina. Prozerin is recommended for resuscitation of neuromuscular conduction. It can be combined with other anticholinesterase drugs.

When the pathology is in the acute phase, Prozerin not registered. It is important to remember that these injections are painful.

Surgery

The main goal of the operation is to eliminate compression of the spinal cord. Surgery is prescribed only after comprehensive examination dogs.

Surgery is prescribed to relieve compression of the spinal cord.

During surgery, the veterinarian removes the spinal arches. After surgical intervention the doctor advises the dog’s owners regarding the rehabilitation period.

What's the prognosis?

Severe swelling contributes to compression of the nervous tissue. Against this background, there is a deterioration in blood supply. Access of oxygen to the affected tissue is disrupted, and nerve cells die.

The prognosis depends on the degree of compression. The larger the area of ​​nerve tissue damage, the worse it is. If the animal has impaired defecation and no pain sensitivity, the prognosis worsens.

Therefore, it is very important to notice the onset of the disease. You should immediately contact a veterinary clinic if your dog:

• worries a lot;
• hides from the owner;
• squeals when someone touches her back;
• refuses to play with other animals.

Preventive actions

It is better to take a puppy of any breed in your arms when going downstairs.

Sooner or later, any dog ​​develops problems with its limbs. The owner's task is to reduce the risk of developing dangerous diseases. To do this, you need to follow preventive recommendations.

Puppies of heavy breeds need to be given chondroprotectors. This must be done continuously until the child reaches 12 months of age. Dachshunds and large dogs up to 10 months. you can't jump. Playing with large adult animals is not recommended.

Before reaching six months of age Puppies of any breed must be carried in your arms when going down.

• They rise on their own. This helps strengthen muscles .
• Animals prone to dysplasia are shown periodic x-ray examination . This will help to detect the disease in a timely manner.
• It is important to provide your pet sufficient level of physical activity . Their excess is just as harmful as lack of activity.
• The dog's diet should be balanced . Until the age of six months, the animal should be given special food for young dogs. The pet's diet should be rich in vitamins and other substances necessary for the body.

• It is important to protect your dog from drafts. Otherwise, there is a risk of catching a cold in the spine.
• It is advisable to minimize the risk of injury. This will avoid the development of dangerous pathologies.

The dog should be protected from possible drafts.

Video about hind leg failure in dogs

You may notice the first signs of a problem while walking. If they appeared after sudden movements(for example, during games), then do not consider activity as the cause of illness. Quicker, .

Symptoms of hind leg failure in dogs are extremely unpleasant:

• The dog cannot move normally

• Hind legs weaken and become unruly

• As a result, paralysis of the pelvic limbs or paresis may develop.

Manifestations of the disease do not always occur all at once. Sometimes in the morning the dog feels pain, and in the evening the deplorable signs and consequences of paralysis of the limbs are already obvious.

Causes and diseases leading to hind leg failure in dogs

The disease can cause discouragement among owners, since everything happens quite abruptly and unexpectedly.

There can be many reasons for it:

• Limb injuries: fractures, nerve damage, tendon ruptures and sprains.

• Arthritis of the extremities

• Spinal pathology

If the spinal cord is affected in the thoracic or lumbar region spine, paralysis or paresis may develop. However, injuries are also risk factors. Sometimes a sharp turn, a fall, a blow, a bite during a fight with another individual provokes a whole chain of problems. Keep in mind that the dog may slip on the ice, jump unsuccessfully, or turn around. If possible, monitor your pet to reduce risk factors.

Nervous system

One of the most common causes of hind leg failure in dogs that owners encounter is problems nervous system.

Neurological disorders manifest themselves as follows: in the thoracolumbar region of the dog’s spinal column, strong pain. Then paws are taken away, and it is clear that the animal cannot move its limbs. Eventually pain sensitivity disappears. You may notice the first signs of a problem while walking. If they appear after sudden movements (for example, during games), then do not consider the activity to be the cause of the disease. Quicker, movement provokes symptoms of an existing problem.

This problem is typical for small and medium-sized dogs rather than large breeds, as well as individuals with a genetic predisposition to damage to the intervertebral discs. The main risk group is dachshunds; the problem is observed in French bulldogs, Brabançons, Pekingese and other representatives of brachycephalic breeds. Most often, unpleasant changes are observed between the ages of three and eight years.

Some dachshund owners think that the problem lies in the long spine. However, science does not confirm this guess. And it is interesting that the manifestations of the disease do not always appear all at once. Sometimes in the morning the dog feels pain, and in the evening the deplorable signs and consequences of paralysis of the limbs are already obvious.

Injuries

Pathology develops in stages: First, the structure of the spinal column is disrupted at the site of injury, then swelling occurs. This causes the spinal cord and radicular nerves to become compressed. The latter problem leads to the disruption of the flow of blood with oxygen.

When this lasts for some time, nerve cells die and are blocked nerve impulses along peripheral nerves.

A severe injury violates the integrity of the spinal cord tissue, in other words, it ruptures it. It is clear that this is critical for any animal, and the help of a specialist is needed.

Degenerative diseases of the spine

Sometimes the spine can simply fall under the influence of degenerative processes. This also leads to the fact that the dog’s hind limbs stop working normally. In this case, the metabolic processes in the tissues of the body, and the parts of the spinal column undergo pathological changes.

Spondylosis

Your dog's hind legs may also fail due to so-called “local aging,” or spondylosis, of certain areas of the spine. This disease goes away quite slowly. It may be almost invisible at an early stage. The outer fibers of the annulus fibrosus are damaged first. Then a process called calcification in medicine occurs with the anterior longitudinal ligament. Beak-shaped growths appear on the spine, they are called osteophytes.

Tumors in the spine

Tumor-like processes sometimes occur in the spine and in the spinal cord itself. As a result, pathologies gradually develop, and in some cases, fractures of the spinal column. If the process sharply worsens, the developing edema compresses the roots and spinal cord. This results in the following symptoms:
limbs are weakened or compressed,
the back arches,
gait is disturbed,
the dog squeals while trying to make the usual movements,
refuses food.

Spondyloarthrosis

Joints of the spine - weakness dogs diagnosed with osteochondrosis. If they are subjected to static loads, the joints can become deformed. The phenomenon is called spondyloarthrosis. Uneven loads on the spinal column are also dangerous. They lead to vertebral hernia: due to pathology, the fibrous ring changes, and as a result, the nucleus pulposus of the intervertebral disc protrudes. The hernia compresses the radicular nerves and sometimes the spinal cord itself.

Discopathy

Diseases of the intervertebral discs, also called discopathy, cause neurological damage to the pelvic limbs. The disc substance changes and enters the spinal canal. As a result, it is clamped:
or the spinal cord itself,
or spinal nerve roots.
Neurological deficit is a consequence of these processes.

When a large dog's paws fail, the problem has its own characteristics. In Dobermans, German Shepherds, Great Danes, Rottweilers and similar breeds, the disease progresses gradually over several months or years. It can be assumed that damage to the intervertebral discs has occurred - in the lumbar region or near the lumbosacral junction.

French bulldogs are especially susceptible to discopathy. This is due to their unnatural anatomy, which resulted from artificial selection. The spine of this breed has become elongated, which leads to greater stress on it. The situation is aggravated by the fact that the distance between the vertebrae is greater than normal. As a result, even at rest it may fall out. intervertebral disc, and even more so during active movement.

Dysplasia

Heavy breeds have their own problem - diseases of the musculoskeletal system. Saint Bernards, Shepherds, Labrador Retrievers, Great Danes characterized by intensive growth at the age of 4-10 months. This is partly why puppies of these breeds suffer from hip dysplasia.

Pay attention to the first symptoms! If a dog limps after sleep or a passive state in a lying position, and then “paces” during the day, these are the first signs, after which it is advisable to call the veterinarian home or take the dog for an x-ray. If the dog is not treated, the symptoms may worsen, and a prolonged problem may lead to complete refusal animal from walking.

Osteocondritis of the spine

The most severe form of damage is spinal osteochondrosis. In this case, discopathy becomes more dangerous form- degenerative processes move from the intervertebral discs to the surrounding vertebral bodies. The ligaments and intervertebral joints are also affected.

Here are some common causes of osteochondrosis:
Genetic developmental defects. Because of this, the vertebrae function unstable.
Spinal injuries.
Autoimmune processes.
Rheumatoid lesions.
Microcirculation is disrupted, and as a result, the nutrition of the disc is disrupted.

Spinal pathology

Blows and bites, falls and unsuccessful jumps, as well as other unfavorable factors lead to spinal pathology. This phenomenon leads to paresis and paralysis. The spinal column ceases to be integral, its structure is disrupted and swelling occurs. The spinal cord and radicular nerves are compressed.

What to do if your dog's back legs fail?

Unless you have special skills, knowledge and experience, you will most likely need a veterinarian. A doctor whose specialty is neurology will be especially helpful.

Now let's look at common questions.

Is it worth contacting if the first symptoms just appear: pain reactions to body movement, tension in gait or refusal of physical activity?

Yes, it's worth it. The sooner you contact, the greater the chances of helping. Even if the alarm is false, you can take the opportunity to do a preventive examination.

If the late stage has already begun - the hind legs have given up, is it worth calling the veterinarian, or is the dog already doomed?

There are always chances. If the animal is dear to you, then try to find out what can be done in the current situation. Even completely immobilized dogs were sometimes brought to their feet. Another thing is that the chances in this case are less.

Practical advice for a critical situation:

• If the dog is injured and, apparently, the spine has been damaged, then in order to take it to the veterinary clinic, secure it to the board with belts or bandages.

• If there is your four-legged friend whines and howls, and the doctor will arrive soon, do not rush to use painkillers - it can contribute to further displacement of the vertebrae.

There is no single reason for the situation in which a dog’s hind legs fail. If the animal drags its paws, wobbles when walking back body, limping, then qualified diagnosis is required, so a visit to the veterinarian is mandatory. There is a common misconception among dog owners that NSAIDs (nonsteroidal anti-inflammatory drugs), such as Diclofenac or aspirin, will help in this case.

Such improvements in condition are temporary and distract from the search the real reason diseases. Therefore, only a doctor should prescribe treatment, and the owner can provide first aid to the pet.

Description of the problem

There is an age-related predisposition to pathologies motor system, also manifestations vary depending on breeds. The following diseases occur in certain types of dogs:

• English and French bulldogs, dachshunds, Pekingese, pugs and poodles are more likely to suffer from ruptured or slipped discs. This is a serious danger to your pet and can lead to death. Displacement of the vertebrae provokes compression of the nerve processes of the spinal cord and causes severe pain attacks. If nerve endings puppies are compressed to a lesser extent, this is manifested by weakness of the hind limbs.
• Large breeds - Rottweilers, St. Bernards, Great Danes, German Shepherds, Staffies and others - suffer from diseases of the hip joints. This is caused by heredity, monotonous nutrition, and uncomfortable slippery ground during daily movement.

Depending on age, the causes of hind limb weakness vary:

• Middle-aged pets suffer from inflammatory processes in the muscles the next day after a long walk or unusual exercise. The dog's gait resembles walking on stilts. Only a veterinarian can distinguish temporary inflammation from spinal lesions.
• In older dogs, poor hind limb function is more often associated with dysfunction of the central nervous system or vascular problems. Tumors are relatively rare.

Causes of the disease

Inattention to a pet, accompanied by prolonged asymptomatic period, ignorance about the state of his body leads to the fact that the animal suddenly has problems with the work of its hind legs.

Diseases of the renal system cannot cause weakness of the limbs and a hunched spine, unless it is weakened to the point of last degree. In this case, lethargy extends not only to the hind legs, but also to all other muscle groups.



Animal injuries

A sprain, fracture, rupture of a tendon or pinched nerve when jumping from high fences, parapets or simply from awkward movements become the main causes of paresis and paralysis. Even small shifts of the spinal discs can provoke pathology.

Sometimes swelling occurs at the site of displacement of the vertebrae, which compresses the nerve endings. Impaired blood flow causes cells to die and impulses to stop, causing the hind legs to fail.



Discopathy

This disease is intervertebral hernia– protrusion of intervertebral discs beyond the spinal column. Because of this, the nerve of the spinal column is compressed and the movement of the paws is impaired. Dog breeds with long spines, such as basset hounds or dachshunds, are more likely to suffer from this disease. In other dogs, the manifestations of discopathy may not be very pronounced.

As a result of selection, the spine of French bulldogs has become longer, so representatives of the breed are more likely to suffer from this disease. These dogs need to be protected from heavy loads and ensure that they do not make sudden jumps from heights.



Dysplasia

This disease is difficult to treat. In pets, dysplasia occurs due to abnormal development of the hip joints as a result of heredity or dislocation at birth. Because of this, all systems of the joint unit cease to function normally. The cause of dysplasia is fast growth puppy.

When buying a shepherd, Labrador, Great Dane or St. Bernard (we are talking about large breeds), you need to require not only a pedigree, but also tests to check for dysplasia of the parents. If the pet begins to get tired, its gait becomes wobbling, then an x-ray will help identify the disease.



Osteocondritis of the spine

This disease often occurs after discopathy and is characterized by excessive mineralization of cartilage tissue, which as a result hardens and causes joint destruction. At the same time, ligaments and vertebrae are destroyed.

The main factor in the pathogenesis of the disease is heredity. Blood microcirculation is disrupted, autoimmune processes change, and excess weight. More often the disease affects representatives of small breeds, but people also get sick big dogs. The disease hampers the movement of the hind legs, although no other symptoms are observed, this leads to the fact that over time the dog’s limbs fail.

Arthrosis and arthritis

These diseases cause poor functioning of the dog's limbs. They are typical for animals of heavy, massive and large breeds. The joint becomes thinner with arthrosis cartilage tissue, the heads of the joints rub against each other and are gradually destroyed, which leads to severe pain when moving.

Arthritis suggests inflammatory process, and arthrosis destroys bones without inflammation. Arthritis is more common in older pets, and there is inflammation of the joint capsule, which is caused by a lack of vitamins in the diet, excess movement or lack of exercise, and obesity of the animal.

Sometimes the dog cannot move its limbs a short time, then the ability to walk is restored. Such cases require mandatory consultation with a doctor.

General symptoms of pathology

Diseases can appear suddenly and develop rapidly, or the build-up of symptoms occurs gradually and takes a long time. Sometimes the signs are unclear, much depends on the reason for the failure of the hind legs:

• The main symptom in all cases is pain, which is pronounced or dull. At the beginning of the disease, the dog does not fall on his feet, only during a walk the coordination of movements of the rear part of the body is disrupted, and a wobbling gait appears. The animal walks poorly, sometimes it simply drags its legs behind it, and to move it pulls itself up on its front legs.
• Pain occurs in a pet after an active walk or play. An attentive owner will notice this condition immediately; usually the dog’s legs give way.
• Severe pain syndrome leads to the fact that the animal cannot walk, falls and tries to get up again. Often the pet panics. The condition, in which the paws hurt, can appear temporarily, while the dog is lethargic and does not eat.
• Constant pain depletes the dog's strength. Not only does she not move or run, but she also cannot stand up and trembles all over.
• The worst manifestation of the disease is numbness in the hind legs. The muscles do not react to injections with a sharp object, the pet does not move its limbs. In this case, we are talking about paralysis or paresis, which requires immediate veterinary attention.

First aid

First aid for limb failure is to call a veterinarian at home. There are cases where the mobility of legs in completely hopeless animals was restored, so the owner should not panic. First aid measures:

• If the dog is injured and the owner knows about it, then you should try to limit the animal’s movements as much as possible. To do this, place a board or other flat and long object under the pet’s body and tie or bandage the dog to it.
• You should not give painkillers, as this will blur the picture of the disease. Also, the pet, without feeling pain, rips off the bandage or tries to run, aggravating the disease of the joints or spine.
• You cannot massage the animal’s paws or back, or force it to rise. At such moments, the pet does not need food, so you should not feed it. An animal that has fallen into a panic is reassured in an even voice, trying to reduce anxiety.

Animal treatment

Only a veterinarian provides specialized care. The doctor may prescribe surgery, if there are threatening injuries or damage to the spine and pelvic bones is suspected. For diagnosis, ultrasound, myelography are used, urine and blood tests are taken, and other studies are carried out on the recommendation of a veterinarian.

To treat dogs with lesions of the hip joints, spine and spinal cord, the same drugs are used as for humans. It is dangerous to use such drugs independently to treat animals. This is especially true for pets of small breeds, since the wrong dose of medication can kill them. Many medications are prescribed based on body weight.

The effect of treatment most often occurs if contact with a specialist was timely. Usually this is the time when pain symptoms, but paresis and paralysis have not yet developed. During such a period, drug treatment will help avoid irreversible consequences.

Therapeutic measures for failure of the hind limbs include several procedures in combination; their purpose depends on the age of the animal, the severity of the lesion and the causes of the disease. The doctor prescribes painkillers, immunomodulatory, anti-inflammatory, vitamin preparations, and chondroprotectors. During the operation, hemostatics, antihistamines, and antibiotics are used.

Traditional methods

All folk recipes must be discussed with a veterinarian. Unlike a person, an animal cannot tell about its health, so you need to pay close attention to your pet during such treatment. Some folk remedies for dog therapy:

• To reduce pain at home, warming local procedures are performed. For dogs, warm bags with sand, cereals, and salt are most often used, which are applied to the lumbar or hip area. You can use woolen items folded several times and heated with an iron. All warming is done after evening walks, so as not to cool the problem areas after the procedure.
• They practice rubbing the back or thigh with compositions based on honey, alcohol, and propolis. For this you can take irritants, for example, hot red pepper, mustard, turpentine.
• To reduce swelling of problem areas, use herbal infusions and decoctions that have a diuretic effect. These include products from lingonberry leaves, cranberries, bay leaf, corn silk and other ready-made diuretics pharmacy fees. It is advisable to give them to the dog separately, without adding them to the drinking container, as this reduces the effectiveness of the medications.

Preventing problems

To treat limb paralysis, the disease must be recognized in the early stages. If neurological disorders are inherent in genes, then it is not always possible to correct the situation, but you can try to reduce the consequences of the disease.

Timely examination helps to identify tumors that put pressure on nerve endings and disrupt motor activity. They need to be removed to improve the animal's quality of life. There should be no slippery base in the walking enclosure; it is unacceptable to make a cement or concrete screed, which leads to hypothermia of the paws. The best option is the ground or boards.

The diet should include all the minerals and vitamins the dog needs. To do this, consult a veterinarian and introduce it into the diet. vitamin complexes for animals, depending on age and body weight.
