Dog Degenerative Myelopathy Welfare

Degenerative myelopathy is a progressive spinal cord disease in dogs that causes gradual paralysis. Supportive care can maintain quality of life for extended periods.

Key Facts

DM is most common in German Shepherds, Boxers, and Pembroke Welsh Corgis
It is associated with a mutation in the SOD1 gene in affected breeds
Early signs include pelvic limb weakness and dragging of rear feet
Progression to complete paralysis typically occurs over 6-18 months
DM is painless; dogs maintain mental alertness and appetite through the disease

Welfare Considerations

Dogs with DM face progressive loss of mobility while retaining cognitive function and pain-free status. Quality of life assessment focuses on ability to enjoy activities, maintain hygiene, and experience positive interactions. Wheelchairs, physiotherapy, hydrotherapy, and nursing care can extend good-quality life significantly. When incontinence becomes unmanageable or the dog can no longer maintain positive experiences, euthanasia is considered compassionate.

What You Can Do

Begin physiotherapy early to slow progression and maintain muscle mass
Consider a rear-end wheelchair when hind limb weakness becomes moderate
Protect skin from urine scald with frequent cleaning and barrier products
Assess quality of life regularly using a veterinary QoL scoring tool
Connect with DM support communities for practical caregiving advice
