Shih Tzu

The flowing coat makes it easy to forget the Shih Tzu has a flat face, yet it sits in the moderate-risk group of the 2026 Cambridge study, where between half and three quarters of dogs showed some sign of airway disease. A breathing grade has been a recognised Royal Kennel Club test since August 2026. Eyes are the breed's minimum check, and UK vet records show more corneal ulcers and disc disease in Shih Tzus than in dogs overall, so ask for a current eye certificate on both parents. The short jaw crowds the teeth, so plan for regular dental care and keep the hair around the eyes trimmed.
