IVDD causes acute or chronic spinal pain and neurological deficits in affected dogs, requiring prompt treatment to maximise welfare outcomes.
Acute disc herniation causes severe spinal pain and can progress to paralysis within hours. The welfare cost of untreated IVDD is significant - spinal pain is among the most severe pain experienced by dogs, and the anxiety of paralysis likely adds psychological distress. Prompt surgical intervention for cases with neurological deficits provides the best welfare outcomes by preventing permanent paralysis.
