Norwich Terrier

Prick-eared where the Norfolk's ears fold, the Norwich is an affectionate, bustling little dog that usually gets on with other dogs and adores company. The breed carries a known breathing problem, Norwich Terrier upper airway syndrome, which can cause noisy breathing and poor tolerance of heat and exercise despite the normal-length muzzle. Ask whether the parents have had airway checks, and skip hard exercise on hot days. The coat is hand-stripped like the Norfolk's, and small pets are still fair game.
