Dog Syringomyelia in Cavalier King Charles Spaniels

Syringomyelia is a painful neurological condition caused by skull malformation in Cavalier King Charles Spaniels, representing a breed welfare crisis requiring urgent reform.

Key Facts

Over 95% of Cavalier King Charles Spaniels have Chiari-like malformation by MRI examination
Fluid-filled cavities called syringes form in the spinal cord, causing neuropathic pain
Affected dogs scratch at their neck, face, and shoulder without touching the skin - a characteristic sign
The condition is directly caused by breeding for an abnormally small skull relative to brain size
The Cavalier Health organization and breed clubs promote MRI screening programs for breeding stock

Welfare Considerations

Syringomyelia causes severe, chronic neuropathic pain in affected dogs, often described as comparable to phantom limb pain in humans. Dogs live with relentless discomfort that disrupts sleep, exercise, and normal behavior. The tragic reality is that this suffering is largely a consequence of deliberate breeding selection - the breed standard values skull shape characteristics that directly cause the condition. This represents one of the clearest cases in which breed welfare requires fundamental reform of breeding practices rather than just medical management of inevitable outcomes.

What You Can Do

Advocate for Cavalier breed standard reform to allow larger skull size and reduce malformation prevalence
Never purchase Cavalier King Charles Spaniels from breeders who do not MRI screen breeding stock
Support the Cavalier Health organization and their breeding guidelines
Lobby kennel clubs to require MRI health screening for Cavalier breeding registration
Consider adopting rather than purchasing Cavaliers to avoid supporting irresponsible breeding
