Energetic and feisty, the Yorkshire terrier's small size belies its true personality. Ideal for a person who wants to dote over a dog, the Yorkie thrives on attention and affection. Yorkshire terriers make excellent watchdogs. However, they can be snappy toward other children if not treated respectfully or gently. Some might also be aggressive toward other small animals, but some Yorkies live quite peacefully with other dogs and even cats. The breed is sensitive to cold and prone to chills, so Yorkies need to be protected from bad weather. If walked outside when it is chilly, a dog coat is in order. Yorkies are known for their long, flowing, silky coats, which swish around the show ring. The bonus is that Yorkies don't have an undercoat so their coat doesn't shed anymore than your hair does.
