Sealyham Terrier

ConfidentAlertPlayfulIndependentStubborn streak

The Sealyham Terrier is a sturdy, confident little dog with a bold streak and a good sense of humor. He is alert and watchful, quick to announce visitors, and often more independent than his size suggests. With children who are respectful and gentle, he can be a playful companion, though he tends to be wary of strangers and can be firm with other dogs, especially same-sex ones. Early socialization helps him stay relaxed around new people and pets.

Day to day, he does best with regular walks, short training sessions, and a few games that engage his nose and his mind. He is a terrier at heart, so he enjoys digging and chasing, and he needs supervision around small animals. Consistent, positive training works well, since he can be stubborn if bored or pushed too hard.

Living with a Sealyham Terrier

Exercise

Two daily walks of 30 to 45 minutes, plus games like fetch or sniffing activities. He enjoys puzzle toys and short training sessions that keep his mind busy.

Grooming

His harsh, wiry white coat needs regular brushing and stripping or trimming to stay neat, and it sheds only lightly. Occasional baths and checks of the ears and eyes are usually enough.

Health

The Sealyham Terrier can be prone to certain eye and skin conditions and some inherited issues. Ask a veterinarian about health screening and what to watch for in a puppy from a breeder.
