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.
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.
