Dog Degenerative Myelopathy Welfare

Degenerative myelopathy is a progressive spinal cord disease in dogs causing gradual paralysis with no effective treatment currently available.

Key Facts

German Shepherds, Corgis, and Boxers are most commonly affected
Caused by mutations in the SOD1 gene also associated with human ALS
Signs begin with hindlimb weakness and progress to complete paralysis
The disease is painless in its early stages but disability is profound
Genetic testing identifies carriers and affected dogs before symptoms develop

Welfare Considerations

Dogs with degenerative myelopathy face a progressive loss of mobility while remaining mentally alert and engaged with life. Intensive physiotherapy and use of wheelchairs extend quality mobility. The decision about when disability becomes incompatible with quality of life is a difficult but important welfare consideration.

What You Can Do

Consider genetic testing for DM-associated mutations in susceptible breeds
Provide intensive physiotherapy to slow functional decline
Invest in a well-fitted dog wheelchair when mobility is lost
Monitor for signs that quality of life is declining
Work with your vet to plan compassionate euthanasia at the right time
