Japanese Chin

Easy to file under low-risk toy breeds, the Japanese Chin was the second most affected breed in the same 2026 Cambridge study, with around 82% of dogs showing signs of airway disease and fewer than one in five having open nostrils. Ask for the parents' breathing grades, recognised by the Royal Kennel Club since August 2026, and an eye certificate, since the wide-set, prominent eyes are prone to scratches and ulcers. Slipping kneecaps and heart murmurs from valve disease are also reported in the breed, so a vet's check of knees and heart on both parents is a fair request.
