A breed standard is a breed organization’s blueprint of what the ideal dog should look and act like. This is what a show dog like a purebred Boston Terrier is judged against. Instead of being compared to the other dogs in the ring, the dog is compared to how well they fit the breed standard. This is usually what breeders strive to achieve in their breeding programs. A breed standard is the Holy Writ of the dog world.

Consequentially, not many Boston Terriers come anywhere near matching the breed standard and are cut from breeding programs or abandoned because of their imperfections. If you find a cute little black and white dog in your local shelter and wonder what breed he or she could be, a look at the Boston Terrier breed standard can help. Identifying a shelter dog’s breed can help let you know what you are getting yourself in for.

But the looks of a Boston Terrier is a winner, too. You might see a lot of solid colored Boston Terriers that are all black, all grey or all brindle. Or, perhaps their heads are all black. They are still purebred Boston Terriers, but they would be disqualified from the show ring. Only colored and white Boston Terriers, with a certain amount of white on the face as well as body, are allowed to show.

The breed standard also emphasizes sturdiness. They are not to have physical weaknesses like swaybacks, spayed legs, very slow gait or look overly muscular. Their bodies should look sturdy but everything should be in proportion. And the tails are naturally very short, although occasionally a purebred is born with a long tail. The ears are perky and most of the time they are pointed (occasionally a floppy eared one comes along).

But part of the Boston Terrier breed standard that best helps you identify one of this breed is the temperament. Thankfully, the temperament in a Boston Terrier has always been considered just as important as their looks. Boston Terriers were bred purposefully to be companion animals. They are happy, trainable, lively and like to get along with others.

The breed they most look like is the French Bulldog.

The Boston Terrier breed standard not only tells you what to look for in a champion show dog, and how hard it is to find one, but also lists common physical faults of the breed. This can help you identity a dog in a shelter that you might want to adopt.

Boston Terriers are usually abandoned through no fault of their own, but because they are so cute and small, as people often buy them on impulse.
