West Highland terrier

Standing 10 to 11 inches at the shoulder, with dark piercing eyes, compact body, and a carrot-shaped tail wagging with delight, the Westie’s looks are irresistible. Beneath the plush-toy exterior, though, is a true working terrier of gameness and courage. Bred to hunt rats and other underground rodents, Westies are surprisingly strong and tough. The all-white double coat is hard to the touch, not soft and fluffy, according to AKC.

Alert and active, Westies exhibit traits of a plucky and self-reliant ratting terrier: They require no pampering, they will chase after anything that moves, and their independence can make training a challenge. But, thanks to their faithfulness and keen intelligence, Westies will train nicely with time and patience, according to AKC.
