Boston Terriers are compact little dogs with broad heads, protruding eyes, and a tuxedo-patterned coat. Bostons have square faces with short muzzles which resemble the face of a Boxer. Their roots are in the bulldog lines, but Bostons, with their square proportions, are built more like terriers. The ears are small, erect and may or may not be cropped. Their short tails are set low on the body, taper, and can be either straight or screwed. Their smooth, short coat comes in black and white, seal and white or brindle and white.
Size and Weight
Boston Terriers are small dogs who stand between 12 and 15 inches at the shoulder and weigh between 10 and 25 pounds. The AKC has three size classifications: under 15 pounds, 15 to 20 pounds, and 20 to 25 pounds. Any dog who weighs less than 10 or more than 25 pounds is undesirable by breed standards.
Coat and Color
Boston Terriers have a fine, smooth coat that lays flat against the body. They come in three colors: black, seal, which appears black but is actually red, or brindle. All Boston Terriers have white muzzles, face blazes, and chests, which makes them look as through they are wearing a tuxedo. Bostons do not come in solid colors. Breeders with solid-color dogs are not adhering to proper standard, and solid-colored Bostons are immediately disqualified in the show ring.
Grooming a Boston Terrier is a snap. This breed sheds lightly throughout the year, so weekly brushing is enough to keep dead, stray hairs in check. They only need to be bathed as needed, when they get particularly dirty. Some owners find that a dry shampoo helps keep the dog clean, the coat healthy, and further minimizes the need for a bath. Their faces should be cleaned daily, as their protruding eyes can easily become irritated or pick up an infection.
Weekly ear and teeth cleaning will keep harmful bacteria at bay, and Bostons who don't wear their nails down naturally will need a monthly clipping.
