 They also have a deep chest, muscular limbs, a black nose, and a short, closely fitted jaw with "scissors" bite (lower canines locked in front of upper canines, upper incisors locked over lower incisors). The Westie's paws are slightly turned out to give it better grip than flat-footed breeds when it climbs on rocky surfaces. In young puppies, the nose and footpads have pink markings, which slowly turn black as they age.
