Dog Degenerative Myelopathy Care

Degenerative myelopathy is a progressive neurological disease in dogs requiring dedicated supportive care and quality-of-life management.

Key Facts

DM is a progressive disease of the spinal cord caused by a mutation in the SOD1 gene.
German Shepherds, Pembroke Welsh Corgis, and Boxers are most commonly affected.
The disease typically begins with rear limb weakness and progresses to paraplegia over 6-18 months.
There is no proven treatment to halt progression; physiotherapy and exercise slow the rate of decline.
Genetic testing can identify carriers and at-risk individuals before breeding.

Welfare Considerations

DM is a degenerative condition that causes progressive loss of mobility without pain in the early stages. As the disease advances, affected dogs lose the ability to walk, then stand, and eventually lose bladder and bowel control. Quality of life assessment must be ongoing and honest; many dogs adapt remarkably well to wheelchairs and maintain good quality of life for extended periods. However, the final stages involve complete paralysis and significant nursing needs. Physiotherapy, hydrotherapy, and appropriate assistive devices substantially extend comfortable life, but the trajectory requires frank conversations with owners about end-of-life planning.

What You Can Do

Begin physiotherapy and hydrotherapy immediately upon DM diagnosis to slow progression.
Invest in a quality canine wheelchair when rear limb function deteriorates significantly.
Use validated quality-of-life scales monthly to support objective end-of-life planning.
Choose breeders who test for the SOD1 mutation in predisposed breeds.
