Dog Degenerative Myelopathy: Care and Progression

Degenerative myelopathy is a progressive spinal cord disease affecting dogs. Understanding its trajectory helps owners plan for quality-of-life maintenance.

Key Facts

Degenerative myelopathy most commonly affects German Shepherds and Corgis
It is caused by a mutation in the SOD1 gene in most affected breeds
Progressive hindlimb weakness typically begins between 8 and 14 years of age
There is no cure; treatment focuses entirely on quality-of-life management
Physiotherapy and hydrotherapy can slow functional decline

Welfare Considerations

DM is a deeply challenging condition for dogs and owners. Dogs remain mentally alert and engaged even as physical function deteriorates — this disconnect makes welfare decisions particularly complex. Regular physiotherapy and range-of-motion exercises help maintain mobility. Wheelchairs can extend the time a dog can engage in exercise and social interaction. Monitoring for faecal and urinary incontinence, skin sores and respiratory changes helps guide end-of-life discussions.

What You Can Do

Establish a daily physiotherapy routine with guidance from a canine rehabilitation professional
Use non-slip mats throughout the home to prevent falls
Consider a canine wheelchair when hindlimb weakness becomes significant
Keep nails trimmed and paws protected to reduce knuckling injuries
Monitor quality-of-life using validated assessment tools and discuss honestly with your vet
