It is a disease that affects the spinal cord and leads to loss of hind leg mobility. Degenerative myelopathy SOD1B is a slower form of standard degenerative myelopathy.

Bernese Mountain Dog

A black and white dog with a happy expression is looking up at the camera with its mouth open. The dog's ears are perked up, and it appears to be excited.

What does this mean for a dog with this trait?

There is no known cure for degenerative myelopathy SOD1B. Care for dogs with the condition includes implementing things that make it easier for them to walk, like covering slippery floors with rugs or yoga mats, installing ramps or stairs for tall surfaces, and more. If dogs become fully unable to walk, many turn to euthanasia as a compassionate choice.

Symptoms

Symptoms of degenerative myelopathy SOD1B typically appear around 9 years of age. Dogs with the condition slowly lose both coordination and muscle in their hind legs until they are eventually unable to walk. This process can occur over a 2 year timespan.
