Kerry blue terrier is the national dog of Ireland. It is named after County Kerry, where it originated. It was bred to help herd sheep and cows, and to kill rats and otters. The Kerry blue stands about 18 inches (46 centimeters) high at the shoulder, and weighs 30 to 40 pounds (14 to 18 kilograms). Its coat is soft and wavy. On its head it has a thick tuft, or forelock, which is usually combed down between its eyes. The dog’s beard makes its muzzle appear large and long. Puppies are born black but become blue-gray as they grow older. See also Terrier.
