What this means for your English Toy Terrier (Black & Tan)

Patellar luxation (a slipping kneecap) and Legg-Calve-Perthes disease, a degeneration of the hip joint seen in small breeds, are both worth discussing with your vet. Dental crowding is also common given the breed's small jaw size, so regular dental checks matter throughout life.

As a naturally lean, fine-boned breed, English Toy Terriers can be sensitive to cold — a coat for winter walks is a sensible addition as your dog ages.
