Intervertebral disc disease (IVDD) is a common and painful spinal condition in certain dog breeds, causing disc material to compress the spinal cord and resulting in pain, weakness, or complete paralysis.
IVDD causes significant acute welfare harm. The initial disc herniation event is acutely painful — dogs may cry out, refuse to move, and show postures indicating severe spinal pain. Progression to paralysis removes pain perception in some cases but causes loss of bladder and bowel control, creating ongoing welfare challenges even for pain-free animals. Without surgery, conservative management requires strict cage rest for weeks — a significant welfare imposition for active dogs. The post-surgical recovery period involves weeks of restricted movement and physiotherapy. Recurrence risk in untreated discs remains, and bilateral episodes are common in severely affected breeds. Selective breeding for extreme chondrodystrophic features — particularly the very short legs and long backs of Miniature Dachshunds — is a root cause of this welfare burden that responsible breeders and buyers can address.
