Degenerative myelopathy is a progressive, incurable spinal cord disease that causes hind limb paralysis in dogs, requiring compassionate long-term welfare management and careful end-of-life planning.
DM presents a distinctive welfare challenge because of its painless but relentless progression. Dogs remain mentally alert and engaged throughout — their minds remain sharp even as their bodies fail — which creates profound quality of life questions. In the early stages, dogs adapt remarkably well to weakness, and physiotherapy and assistive devices (rear-end harnesses, dog wheelchairs) can maintain meaningful quality of life. As paralysis ascends to involve bladder and bowel function, the welfare situation becomes more complex: urinary and faecal incontinence require intensive nursing care to prevent urine scalding, pressure sores and infection. Dogs using wheelchairs often show joy during mobility sessions but require careful monitoring for skin integrity. The timing of euthanasia is emotionally difficult — owners often delay because the dog remains bright and engaged despite physical limitation, but prolonged incontinence and immobility eventually compromise welfare significantly.
