Understanding IVDD in Dogs

Intervertebral Disc Disease (IVDD) is one of the most common spinal conditions in dogs. It occurs when the discs between the vertebrae of the spine degenerate, herniate, or rupture, putting pressure on the spinal cord. This can cause pain, nerve damage, weakness, and in severe cases, paralysis.

Which Dogs Are at Risk?

IVDD most commonly affects chondrodystrophic breeds — dogs with long backs and short legs:

• Dachshunds (highest risk — up to 25% will develop IVDD)
• Pembroke Welsh Corgis
• Beagles
• Basset Hounds
• Shih Tzus
• Bulldogs
• Cocker Spaniels

Symptoms of IVDD

• Reluctance to jump or climb stairs
• Back pain or sensitivity when touched
• Shaking or trembling
• Hunched posture
• Weakness or dragging of the rear legs
• Paralysis of the hind limbs
• Loss of bladder or bowel control

IVDD Stages

• Stage 1: Mild pain, no neurological deficits
• Stage 2: Moderate to severe pain, mild weakness
• Stage 3: Significant weakness, difficulty walking
• Stage 4: Paralysis but can still feel pain
• Stage 5: Paralysis with no deep pain sensation

Treatment Options

• Conservative (Stages 1-2): Strict crate rest 4-6 weeks, anti-inflammatory meds, pain management
• Surgical (Stages 3-5): Decompression surgery to remove herniated disc material, followed by 6-8 weeks crate rest

Prognosis

• Stages 1-3: 90%+ recovery rate
• Stage 4: 85-90% recovery with surgery
• Stage 5: 50-60% if surgery within 48 hours
