If your pet is experiencing weakness in their hind legs, we recommend reading this article. Our veterinarians at Boulder County can provide guidance on how to improve or maintain their leg strength.
What causes sudden hind leg weakness in dogs?
There are various factors that can lead to your dog's back legs slipping or giving out. Let's explore some of these causes.
Canines, like humans, can suffer from arthritis. Osteoarthritis is a type of arthritis that primarily affects the hind legs. This happens when their joints aren't well lubricated, making movement painful. If your pet exhibits any of the following symptoms, you should take them to the vet right away:
- Difficulty climbing stairs or walking
- Bunny hopping while moving
- Development of large front-leg muscles and weakening of rear-leg muscles
If you notice your pet's hip joints are looser than usual, this could be a sign of hip dysplasia. This condition can cause balance problems as well as osteoarthritis in severe cases. It is more common in larger dog breeds, like:
- German Shepherd
- Labrador Retriever
- Saint Bernard
- Great Dane
Hip dysplasia is primarily caused by genetics, but other factors such as size, weight, and overuse may also play a role in developing this condition.
Canine Degenerative Myelopathy
Your pet may have degenerative myelopathy, a condition in which the protective covering of the nerves deteriorates, resulting in abnormal nerve function. Keep an eye out for the following symptoms:
- Quivering hind legs
- Hind legs coming together while standing
- Feet positioned at unusual angles
- German Shepherd
- Cardigan Welsh Corgi
- Rhodesian Ridgebacks
Did you know that diabetes can weaken your pet's hind leg joints? Inadequate insulin production causes abnormal blood sugar levels, which can lead to this outcome. Consider increased thirst and appetite, incontinence, and weight loss as indicators. If you notice these symptoms in your dog, consult a veterinarian and obtain a blood test to confirm the diagnosis.
FCE is a condition that can affect dogs in which a small piece of cartilage obstructs their bloodstream, causing spinal enlargement. The result is temporary hind leg movement restriction and pain, which is more common in larger dog breeds. FCE is common in German Shepherds and Irish Wolfhounds, among other breeds.
It can help restore leg mobility if your pet requires surgery, such as a tibial plateau leveling osteotomy (TPLO). However, your pet may be required to limit physical activity during recovery if the surgeon orders. This restriction may cause temporary impairment, but it is required for a full and successful recovery.
What are the symptoms of my dog's back legs not working?
Because the symptoms of the conditions listed below are so similar, determining the underlying cause without medical assistance can be difficult. As a result, it is critical to consult a veterinarian as soon as possible. If you notice any of the following behaviors in your dog, you must act quickly:
- Hind leg tremors
- Swaying of the hind end
- Trouble transitioning from lying or sitting to a standing position
- Difficulty walking or a complete inability to walk
- Inability to climb stairs
- Sudden reluctance to go for walks or play
- Stumbling and lack of coordination
- Muscle mass loss
- Decreased walking speed in general
Tips on How to Strengthen An Old Dog's Hind Legs
There are non-medical steps you can take to aid in your pet's recovery and restore their vitality after determining the cause of their distress and receiving treatment recommendations.
- It is recommended to take your furry companion for brief yet consistent walks on a daily basis. This will aid in gradually restoring their hind-leg muscles.
- Let your dog swim in a safe place. Swimming provides a low-friction way to work their muscles and benefits their overall strength.
- As dogs age, their metabolism slows down, and excess weight can strain weakening legs. To prevent this, ensure your pet enjoys a healthy diet with lean, protein-rich foods.
- One way to support your pet's joint health and mobility is by giving them supplements that contain Omega-3 fatty acids. These supplements can help reduce inflammation and provide extra nutritional support for aging joints.
- Inflammation-reducing treatments such as acupuncture and regenerative therapy can greatly address limited mobility and reduce pain.
