Siberian Huskies come in a variety of colors and patterns, usually with white paws and legs, facial markings, and tail tip. The most common coats are black and white, then less common copper-red and white, grey and white, pure white, and the rare 'agouti' coat, though many individuals have blondish or piebald spotting. Some other individuals also have the 'saddle back' pattern, in which black-tipped guard hairs are restricted to the saddle area while the head, haunches and shoulders are either light red or white. Striking masks, spectacles, and other facial markings occur in wide variety. All coat colors from black to pure white are allowed. Merle coat patterns are not permitted by the American Kennel Club (AKC) and The Kennel Club (KC). This pattern is often associated with health issues and impure breeding.
