Chiari-like malformation and syringomyelia cause severe, chronic neuropathic pain in Cavalier King Charles Spaniels, representing one of the most serious breed welfare problems in companion animals.
Chiari-like malformation and syringomyelia cause chronic neuropathic pain that profoundly reduces quality of life in affected Cavaliers. The phantom scratching behaviour — dogs scratching at the neck area without making contact — is a distinctive sign of neuropathic pain that is intensely distressing for affected individuals. Pain is often poorly managed because owners and sometimes vets fail to recognise the severity of the neurological pain burden. The genetic basis of the condition requires breeding reform — MRI screening programmes and selection away from excessively small skull-to-brain ratios are essential long-term welfare interventions.
