19. Sealyham Terrier

Hidden behind lavish tufts of hair that covers its face, the Sealyham terrier is the feisty comedian of the terrier world. Extremely affectionate, they make excellent companions and pack a lot of personality inside their small stature. Their white, waterproof coat doesn't shed. Despite their sweet and expressive appearance, they bark with the ferocity of a big dog, which also makes them a great watchdog. Sealys easily adapt to both city and country living. Breeders developed the breed with crosses between Corgis, Dandie Dinmonts terriers, West Highland terriers, Bull terriers, and others.
