Intervertebral Disc Rupture in Dogs: Paralysis Risk and Emergency Care

Herniated intervertebral discs (IVDD) can compress the spinal cord, causing pain, neurologic deficits, and paralysis—especially in chondrodystrophic breeds (Dachshund, French Bulldog, Corgi, Beagle).

Clinical Grading (1–5)

1. Pain only
2. Ambulatory paresis (weak, wobbly)
3. Non-ambulatory paresis (cannot walk, voluntary movement present)
4. Paraplegia (no voluntary movement, deep pain present)
5. Paraplegia with absent deep pain perception (poor prognosis)

Emergency Signs

• Sudden inability to walk
• Dragging limbs
• Urinary/fecal incontinence
• Severe pain (hunched, crying)

Management

• Grade 1–2: Strict crate rest 4–6 weeks + anti-inflammatories ± muscle relaxants; ~80% recover.
• Grade 3–4: Surgery (hemilaminectomy) preferred; medical management possible but lower success.
• Grade 5: Emergency surgery <24h for best chance; prognosis guarded.

Prevention

• Weight control
• Harness (not collar) for walks
• Ramps/stairs for furniture
• Avoid high-impact activity

Neurologic deterioration = surgical emergency. Early referral to neurologist improves outcomes.
