Dachshunds are predisposed to intervertebral disc disease (IVDD) due to their chondrodystrophic body form, causing spinal cord compression and paralysis. The breed's popularity despite this known welfare issue is a major concern.
Dachshunds experiencing acute IVDD suffer extreme spinal pain, potentially described as the most severe pain a dog can experience. Paralysis following disc herniation causes loss of bladder and bowel control and inability to walk. Even with surgical treatment, recovery is not guaranteed and rehabilitation requires intensive support. Breeding selection for shorter legs and longer backs — traits associated with higher IVDD risk — continues despite the welfare burden they impose.
