Bostillon Breed History

The name Bostillon is a combination of the two names of its parent breeds: the Boston Terrier and the Papillon. The Boston Terrier was recognized by the American Kennel Club in 1893. A popular breed, it was bred often in Boston, Massachusetts, its origin city after being brought from England, giving us the breed we know today. From 1905 to 1939, the Boston Terrier was the most popular dog in the United States and still holds favor with many. The Bostillon’s other parent breed, the Papillon, got its name because of its butterfly wing shaped ears. The breed originated over 700 years ago in France and was very popular with European royalty and elite. Papillons can even be identified in Italian frescoes and paintings as early as the 13th century. Interestingly, this breed originally had pendant ears. Over time, however, it developed the erect ears that we recognized it by today. In fact, many litters still produce puppies with both types of ears. Papillons became popular in North America during the early 20th century, and the AKC recognized the breed in 1915. The product of these two breeds, the Bostillon, is suspected to have originated in the early to mid-1900s when both parent breeds were in North America. It was likely bred haphazardly or by mistake for some time. Only recently has it been recognized as a designer hybrid, but not by the AKC.

Bostillon Breed Appearance

A Bostillon looks like a true mix between its two parent breeds. It is a small dog with the compact torso and the taller legs of a Boston Terrier. At the same time, it has the relatively longer muzzle, big round eyes, and signature upright ears of a Papillon. Bostillons weigh between 10 and 17 pounds and grow to be between 11 and 16 inches tall. Their coat is short to medium length and soft with feathering around the ears, feet, paws, and underbelly. Bostillons are typically black and white, also known as the “tuxedo” pattern, but can also have other colors common in Papillons such as browns and reds. Bostillons’ large signature ears sit high on their heads in an erect fashion. They have long tails and round, delicate paws that carry its prancing-like gait.

Bostillon Breed Maintenance

Bostillons are not hypoallergenic and thus are not suitable for owners with allergies. They do not require much grooming or bathing since they don’t carry common odors as much as other breeds. However, owners should be cognizant of trimming the feathered parts of their coasts around the eyes, ears, and paws to avoid infections, matting, or debris buildup in those areas. Tangles or matting in these areas should be brushed out as soon as they are noticed. Like all breeds, Bostillons must have their teeth brushed daily and their nails clipped a few times a month to prevent painful overgrowth or breaks.

Bostillon Temperament

Because Bostillons retain many desirable qualities of both its parent breeds, it is known as a wonderful family companion that loves to hang out with its owners. Bostillons are known to be gentle and get along with children, elderly, and other dogs very well. They also enjoy downtime indoors with their owners and family members. They are not a hyper breed and are content with daily moderate walks and a romp in the dog park. Since Bostillons are relatively social, they will bark and whine if left alone for too long. This affectionate hybrid is better suited for homes that have someone present during the day. In fact, it is important to note that this breed tends to be “barky” in general. Otherwise, Bostillons have a generally happy disposition, which make them more adaptable than their Boston Terrier parent. Overall, they are sweet pets that thrive in structured environments where social, exercise, and downtime are relatively consistent.

Bostillon Activity Requirements

The Bostillon is a springy and playful breed that requires daily moderate exercise, social time with other dogs, and lots of human affection. Bostillons enjoy a moderate walk, daily trip to the park, and/or playtime with their owners. They do not, however, tolerate hot weather very well and should not be over exercised in warm temperatures. They are fast and agile runners with a tendency to wander and hunt, so owners should not to leave Bostillons unattended outside. In fact, Bostillons are primarily an indoor dog and will be happiest if they have a healthy mix of indoor and outdoor physical exercise and playtime.
