A Solid Dog
His sloping shoulders allow the typical Boston movement that is stylish without being hackneyed or extreme. The Boston comes only in black, seal (appears black but with a reddish cast), or brindle coat with white markings. White muzzle band, face blaze, and white fore chest are required; a white collar and white markings on the legs are also desirable.
Boston Terriers comes in one size range and three weight ranges. The ideal Boston is 12-14 inches tall, but can be lightweight (under 15 pounds); middleweight (15-20 pounds); or heavyweight (rare at 20-25 pounds). The dogs should not be skinny or spindly but should have the correct body proportions.
