Intervertebral disc disease (IVDD) is a leading cause of sudden paralysis in dogs, causing severe pain and often requiring emergency surgery. Understanding prevention, recognition, and recovery improves welfare outcomes.
IVDD causes acute, severe pain that represents one of the most dramatic welfare emergencies in companion animal medicine. Dogs in acute disc herniation may scream, resist movement, and be unable to walk. The urgency of surgical timing is a welfare imperative — each hour of cord compression reduces the chance of functional recovery. Many owners do not recognize the emergency nature of sudden hindlimb weakness or hesitate due to surgical costs. Post-surgical recovery requires weeks of cage rest, physiotherapy, and bladder management that are demanding for owners but essential for welfare. Dogs that regain ambulation often return to good quality of life. Prevention through weight management, disc screening in high-risk breeds, and avoiding high-impact activities (jumping, stairs) reduces IVDD incidence.
