Degenerative Myelopathy in Dogs: Welfare and Progression

Canine degenerative myelopathy is a progressive and ultimately fatal spinal cord disease similar to ALS in humans, causing ascending paralysis that significantly challenges welfare management in affected dogs.

Key Facts

Degenerative myelopathy is caused by a mutation in the SOD1 gene in many breeds
German Shepherd Dogs, Pembroke Welsh Corgis, and Boxers are commonly affected breeds
It begins with weakness and coordination problems in the hindlimbs and progresses to full paralysis
There is no cure or treatment proven to halt progression; physiotherapy may slow functional decline
Average time from diagnosis to inability to walk is 6-12 months in most dogs

Welfare Considerations

Degenerative myelopathy causes progressive loss of function that requires ongoing welfare assessment and management adaptation. As hindlimb function declines, dogs need wheelchairs, slings, and modified environments to maintain mobility and dignity. Incontinence, pressure sores, and secondary complications require vigilant nursing care. Despite the grim prognosis, many affected dogs retain good quality of life in the early and middle stages when mobility aids are available and owners are committed to supportive care. Regular quality of life assessment guides end-of-life decisions.

What You Can Do

Seek early physiotherapy assessment if degenerative myelopathy is diagnosed to maximise functional time
Invest in a properly fitted dog wheelchair when hindlimb function becomes significantly impaired
Monitor for skin pressure sores and maintain meticulous hygiene as the condition advances
Use validated quality of life assessment tools regularly to guide decisions about end-of-life care
