Why Do Old Dogs Back Legs Get Weak?

Why Do Old Dogs Back Legs Get Weak?

Table of Contents

When our beloved pets reach their golden years, it is not uncommon for their back legs to show signs of frailty. Weakness can be caused by various factors, which include joint wear and tear, muscle loss, and more complex disorders such as nerve damage as dogs age. For dogs, this might range from being unable to rise quickly to swaying slightly on their regular walks, which they used to race through. Arthritis, a frequent joint illness in humans and canines, can cause aching joints. 

Alternatively, disorders such as degenerative myelopathy, a type of spinal cord disorder, can cause more serious movement problems. It’s all part of the aging process. Still, like humans, there are techniques to assist in managing and even alleviating some of these symptoms, allowing our four-legged pals to live as happy and mobile as possible into their senior years. Let’s get into the specifics of why elderly dogs may not be as agile on their hind legs as they once were. 

Neurological disorders

Weakness in the legs of elderly dogs can have various neurological causes, as detailed in studies published by Whole Dog Journal. Some of them are:

Degenerative Myelopathy: This is like a silent robber in the night. It progressively creeps up, damaging the spinal cord and gradually causing a loss of coordination and strength in the back legs. It’s more common in particular breeds, and while there is no cure, controlling the symptoms can help maintain quality of life.

Intervertebral Disc Disorder (IVDD): Consider this a horrible case of backache, but much worse. The discs in the dog’s spine might slip or explode, compressing nerves. This can cause multiple symptoms, including discomfort and paralysis. Depending on the severity, treatment options range from rest to surgery.

Let’s get into the specifics of why elderly dogs may not be as agile on their hind legs as they once were. 

Orthopedic Issues

Arthritis:  Dogs, like humans, can develop joint inflammation and pain known as arthritis, which can slow down their morning walks. Treatment options include anti-inflammatory medications, vitamins, and comfortable bedding. 

Hip dysplasia: A joint design fault that is more common in larger breeds. It causes arthritis and discomfort. Its treatment consists of a combination of diet, exercise, and, in some cases, surgery to relieve discomfort.

Osteoporosis is less common but still a worry. It weakens bones, making them more likely to fracture. A balanced diet and exercising regularly might help you manage this illness.

Muscle Atrophy

Lack of Exercise: Like humans, dogs can lose muscle mass when they don’t exercise regularly. This lack of activity can weaken their legs.

Injury: Over time, muscles may shrink and weaken due to previous injuries that limit limb use.

Physical therapy, possibly doggy yoga, and exercises meant to gradually develop strength without overdoing it are all part of the management plan.

Animal Physiotherapy

Animal physiotherapy aims to help dogs regain strength and movement, particularly elderly ones with weak rear legs. It uses a variety of rehabilitation strategies adapted to each dog’s individual needs. 

Hydrotherapy, for example, employs water resistance to help dogs exercise without putting too much strain on their joints, making it excellent for arthritis sufferers. Massage can boost circulation and alleviate muscle tension, hence encouraging healing and flexibility. Specific exercises created by a physiotherapist can target and strengthen weak muscles, improving a dog’s mobility.

Dogs who have trouble with movement can benefit greatly from supportive devices such as wheelchairs or harnesses. These gadgets help the dog by supporting its weight and allowing it to move more freely, thus enabling it to lead an active life within its limitations. Orthopedic shoes can also be helpful as they provide extra support and cushioning for sore joints, making it easier and more comfortable for dogs to walk.

All of these measures aim to improve the quality of life for our aging dogs, enabling them to stay as active and happy as possible.

Nutrition and Supplements

Proper nutrition and specialized supplements are critical in maintaining the health of senior dogs, particularly when it comes to controlling weakness in their back legs. A diet with omega-3 fatty acids and antioxidants reduce inflammation and can improve joint health. Omega-3 fatty acids from fish oil are particularly beneficial due to their anti-inflammatory properties.

Calcium and phosphorus in the proper quantities are necessary for keeping strong bones in dogs, which is especially important as they age and become more prone to illnesses such as osteoporosis. 

Meanwhile, several supplements can provide further support: Glucosamine and chondroitin sulfate are common cartilage protection and repair choices, which may alleviate arthritic symptoms. Another supplement, green-lipped mussel, has been commended for its anti-inflammatory and joint-protective properties.

Genetics and Breed-Specific Preposition

Certain dog breeds are genetically predisposed to illnesses that might cause weakness in their back legs. 

  • Large breeds, Like German Shepherds and Labrador Retrievers, are particularly prone to hip dysplasia. When the hip joint fails to fit together completely, it results in a genetic disorder that causes arthritis and pain in the rear legs.
  • Similarly, breeds with long backs, such as the Dachshund, are more likely to have spinal disorders, which can impair leg strength and movement.

Genetic testing has proven effective in recognizing the risk of these and other illnesses in dogs early in their lives. Understanding a dog’s hereditary predispositions allows owners and veterinarians to develop preventive and management tactics to keep these puppies healthy and mobile for as long as possible. This could involve particular diets, fitness routines, and regular check-ups for early symptom detection. Understanding a dog’s genetic code can help paint a more accurate picture of their future, allowing for preventative care customized to their specific needs.

Preventive Care and Management

Regular exercise and veterinary check-ups are crucial for controlling and preventing back limb weakness in older dogs. The exercise routine should be customized based on your dog’s age, breed, and existing health conditions. Walking and swimming are excellent examples of gentle, low-impact activities that can help maintain muscle strength and joint mobility without overtraining.

Simultaneously, regular veterinary visits are crucial for the early detection of potential health issues. Vets can monitor signs of arthritis, hip dysplasia, or other conditions contributing to leg weakness. This proactive approach to maintaining the health and fitness of our aging canine friends can significantly enhance their quality of life, keeping them active, happy and comfortable for a longer time.

Frequently Asked Questions

1. Why do old dogs start to lose strength in their back legs?

Older dogs experience weakened hind legs due to factors such as arthritis, muscle atrophy, neurological issues, and natural aging.

2. Can arthritis be the reason for my dog's leg weakness?

Yes, arthritis is among the most common reasons for leg weakness in older dogs. Joint inflammation and pain can cause decreased mobility.

3. Are certain breeds more prone to back leg weakness?

Yes, some breeds are more predisposed to conditions that can cause back-leg weakness. For example, large breeds like German Shepherds are more prone to hip dysplasia, while Dachshunds may suffer from spinal issues due to their long backs.

4. What can I do to help my dog with weak back legs?

Helping your dog with weak back legs involves a combination of strategies, including providing a balanced diet, engaging in regular, gentle exercise, managing weight, using supportive therapies like physiotherapy, and consulting your veterinarian for appropriate treatments.

5. Is it normal for old dogs to drag their back legs?

While it’s more common for older dogs to show signs of weakness in their back legs, dragging them is abnormal and could indicate a more serious condition, such as degenerative myelopathy or a neurological issue.
