Canine degenerative myelopathy, which is also known by the name “chronic degenerative radiculomyelopathy”, is a neurological disease that occurs in various dog breeds, such as Welsh Corgis and German Shepherds. This chronic and progressive disease usually manifests in dogs between 5 to 14 years old.

There is no known cure for this chronic disease. However, proper diet and exercise can help in maintaining the infected dog’s quality of life. Aminocaproic acid and n-acetylcysteine could help in preventing the progression of the disease. However, the FDA has not yet approved these medications.

Degenerative myelopathy first affects the dog’s back legs, which causes lack or loss of coordination as well as muscle weakness. Symptoms similar to arthritis may appear. When a dog walks, it may scuff its rear paws, which cause wearing down of nails in the pressured foot. As the disease worsens, it could lead to paralysis of the back legs and develop incontinence as well as balancing and walking difficulties. Severe cases of degenerative myelopathy cause the back legs to become completely useless, which could cripple the dog in a few months. However, the dog could survive up to three years upon the onset of the disease.

The cause of canine degenerative myelopathy is unkown. However, since it occurs commonly in Welsh Corgis and German Shephers, some believe this disease could be genetic.
