IVDD is a common and painful spinal condition in dogs, with welfare outcomes highly dependent on the speed of diagnosis and quality of treatment.
IVDD causes acute severe pain from disc herniation followed by the additional welfare impact of neurological deficits including paralysis. Dogs with acute spinal cord compression experience a welfare crisis: sudden inability to walk, loss of bladder control, and confusion about their loss of function. The prognostic significance of deep pain perception means that rapid veterinary assessment and ideally MRI diagnosis are critical welfare interventions - not just for recovery odds but because prolonged cord compression with maintained pain is a serious welfare concern. Post-operative or conservative management recovery is intensive but achievable; many paralyzed dogs regain full or near-full function with appropriate treatment. Wheelchairs allow paralyzed dogs excellent quality of life when full recovery is not possible.
