Degenerative Myelopathy

Degenerative Myelopathy in Dogs

Degenerative myelopathy (DM) is a progressive neurologic disease that affects the spinal cord in older dogs. It most often causes weakness and loss of coordination in the hind legs. While the changes can be distressing to see, DM is not painful.

Common Signs

Early signs may include a wobbly gait, dragging or scuffing of the rear paws, difficulty standing, or hind-end weakness that slowly worsens over time. Because these signs can look like arthritis or hip problems, DM often goes unrecognized at first.

Diagnosis and Care

There is no single test for degenerative myelopathy. Veterinarians diagnose it by ruling out other causes of hind limb weakness, sometimes with the help of genetic testing. Although there is no cure, supportive care makes a real difference. Physical therapy, mobility aids, non-slip flooring, and weight management can help dogs stay active and comfortable longer.

Quality of Life Matters

DM progresses over months to years, but many dogs continue to enjoy life with the right support. Regular veterinary check-ins help guide care decisions and ensure comfort at every stage.

If you notice changes in your dog’s mobility, talk with your veterinarian. Early evaluation and thoughtful management can go a long way in supporting dogs—and the people who love them.
