Dog Degenerative Myelopathy Welfare

Degenerative myelopathy is a progressive neurological disease affecting older dogs that causes gradual paralysis, requiring compassionate management and quality of life assessment.

Key Facts

DM is caused by a mutation in the SOD1 gene and affects German Shepherds and Corgis most commonly
The disease causes progressive hindlimb weakness leading to complete paralysis
There is no effective treatment to halt progression, though physical therapy slows decline
Dogs typically lose hindlimb function within 6-12 months of diagnosis
Affected dogs remain bright, alert, and pain-free until late stages
DNA testing allows identification of dogs at risk before symptoms appear

Welfare Considerations

Dogs with degenerative myelopathy face a progressive loss of mobility and eventually bodily function, but importantly the disease is not painful during most of its course. Dogs may maintain excellent quality of life for extended periods with appropriate support including wheelchairs, physical therapy, and nursing care for bodily functions. The welfare challenge is maintaining dignity and quality of life as paralysis progresses, and recognizing when loss of continence and inability to position change for comfort signals that quality of life has declined below acceptable thresholds.

What You Can Do

Implement physical therapy and hydrotherapy early after diagnosis to maintain muscle mass
Consider a dog wheelchair to maintain mobility and quality of life as hindlimb function declines
Provide excellent nursing care including regular repositioning and urinary management
Consult with a neurologist about rehabilitation and quality of life management
Use validated quality of life tools to guide end-of-life decision-making compassionately
