Syringomyelia in Cavapoos

Syringomyelia, a condition where fluid-filled cavities develop in the spinal cord due to skull malformation, is rare in Cavapoos but can occur. The hallmark sign is "phantom scratching" — scratching at the air near the neck without making contact. Any dog showing this behavior should be evaluated.

Prevalence

Rare in this breed

Typical Onset

6 months to 4 years

Severity

Severe

Symptoms to Watch For

If your Cavapoo shows any of these signs, monitor closely and consult your veterinarian.

scratching at the neck or ears without making contact (phantom scratching)
yelping or crying out seemingly without cause
sensitivity around the head, neck, and shoulders
reluctance to wear collars or be touched on the neck
wobbliness or weakness
scoliosis (curved spine)

Risk Factors

  • skull conformation abnormality
  • hereditary — autosomal recessive with variable penetrance
  • breeding without MRI screening
  • selection for very round, domed skulls

Diagnosis

MRI is the only definitive diagnostic tool — reveals syrinx (fluid-filled cavities) in the spinal cord and Chiari-like malformation (skull too small for the brain). Grading based on syrinx width. Neurological examination reveals neck pain and proprioceptive deficits. Screening MRI recommended before breeding in Cavaliers.

Treatment

Medical management: gabapentin for neuropathic pain, NSAIDs, omeprazole (reduces CSF production). Surgical option: foramen magnum decompression surgery reduces pressure and can provide significant improvement, though recurrence is possible. Use harness instead of collar. Pain management is lifelong in most cases.

Prevention

MRI screening of breeding stock is the only prevention. The condition is hereditary and linked to skull shape. Choose breeders who MRI-screen parents. International breeding programs are working to reduce prevalence through selective breeding for larger skull-to-brain ratios.

When to See a Vet

See your vet if your dog shows phantom scratching, neck sensitivity, or unexplained pain vocalization. MRI referral should be pursued — many dogs suffer silently without appropriate pain management.
