Pronunciation: [Bos·ton ter·ri·er chə-ˈwä-(ˌ)wä]

The seemingly bizarre cross-breeding of the Boston Terrier and the Chihuahua is not nearly so odd as it may first seem. Both dogs were recognized early on and within a few years of each other by the American Kennel Club, became known in the United States around the same time and have similar personalities. The slightly larger size that may occur thanks to the Terrier along with the more friendly demeanor also helps to make the Chihuahua a little less headstrong. The result is a friendly, active and cute hybrid dog that can adapt to most home environments.

This hybrid can go by a variety of names: the ChiBo, the BoChi, the Bohuahua, or the Boston Huahua. Some owners even call these crossbreeds Boston Chi Parti dogs.

Make no doubt: the Boston Terrier Chihuahua mix is one of those nearly perfect companion dogs. The Boston Terrier originally came from cross-breeding two sporting dogs (one of which is extinct and the other of which long ago had the real fight taken out of it — legally and temperamentally). The Chihuahua was a breed formed several centuries ago by cross-breeding two very different dogs (one of which was believed to be hairless). Despite these differences, the result — all these purebred and crossbred dogs later — is a wonderful, active and fun dog whose intelligence may be a bit challenging but will fit in well with most first-time families.

Boston Terrier Chihuahua Breed Description

The Boston Terrier Chihuahua mix is one of the better designer dogs to emerge from the craze that was based in the 1990s. Although the dogs' histories are very different, they mesh well and have great personalities for family life. Both are small dogs whose previously hyper- and overly bold temperaments have been tempered over the last century — but not so much as to render them boring.

This is easily one of the most intelligent hybrid dogs out there. They are easy to train, love to learn tricks and even tend to show off. You should be aware that this boldness may occasionally become stubborn desire when your BoChi wants something - which is why thorough training should be started at an early age as well as be done with a gentle hand.

She'll be fun, she'll be active — and she may seem like she's too big for her britches at times! Thankfully, her small size will make her manageable, but she is not to be underestimated. These are loyal, loving and fun dogs.

Apartment living will suit a Boston Terrier Chihuahua mix just fine, and while she will find plenty to do on her own, she should be exercised outside at least once daily; left under-exercised and inside she may bark constantly, jump on furniture (and you!) and perhaps even start chewing up things. These dogs may pretend to be stronger than they are, however, and you should use some care when playing with your BoChi.

Boston Terrier Chihuahua Breed History

Because it is a rather new hybrid dog, it is difficult to know what to expect from the Boston Terrier Chihuahua mix. It's unknown why this mixed breed was made or who was responsible. As for the parent breeds, however:

The Boston Terrier is itself a relatively new breed that not so long ago was a crossbreed. The dog was borne of an English Bulldog and a white English Terrier. Unlike many "new" breeds (or most breeds in general), the Boston Terrier has been very well documented from the beginning. The dog that started it all was named Judge; the man responsible was Robert C. Hooper; and the year he introduced this then-named Round Head "breed" was 1870. The American Kennel Club (AKC) formally recognized this dog as a breed in 1893.

The Chihuahua is known for its Terrier-like temperament: it was a bold vermin-hunter that was nevertheless amenable to family life. Mayan art and a former similar breed of dog (the Techichi) indicate the Chihuahua may have been present anywhere from the 5th to the 9th century A.D. The earliest evidence of this dog was found in Chihuahua, Mexico, which is why this dog is so named. Like the Boston Terrier, the breed was recognized early on; formal recognition was granted the Chihuahua by the AKC in 1904.

Boston Terrier Chihuahua Coloring

This hybrid comes in several colors in both solid and patchy patterns. Colors include black, brown, tan, and silver, all of which are often overlaid on white markings. For the Boston Terrier Chihuahua mix, brindle is possible, but not very common.

Boston Terrier Chihuahua Size

Just how big do Boston Terrier Chihuahua mix dogs get? For adult BoChis, average height is 10-12 inches at the shoulders, and weight is 10-15 pounds.

Average Adult Height

8-12 in
*Height is measured in inches from the front paws to the top of the shoulder while the dog is standing on all four legs.

Average Adult Weight

4-10 lbs

Boston Terrier Chihuahua Temperament

Affectionate, intelligent, stubborn, fun-loving, and active, the Boston Terrier Chihuahua mix temperament is an interesting combination of toughness and tenderness. BoChis are usually fun-loving and happy, but the same dogs can also be extremely willful and snippy if they don't get their way. Some may get along very well with kids and other pets, while others may be domineering and selfish; it all depends on luck of the genetic draw. In any case, though, obedience training and socialization--starting early and often--will go a long way towards making your BoChi a more well-balanced dog.

With the combination of the Boston's intelligence and the Chihuahua's stubbornness, training these hybrids can be a challenge. Owners will need to have plenty of patience, and will need to utilize firm, consistent training methods. Short, reward-based lessons are great for BoChis.

And their alert, curious personalities make Boston Terrier Chihuahua mixes great watchdogs, but don't expect them to scare intruders away! They are likely to sound a vocal alarm, though, if they perceive a potential threat.

Boston Terrier Chihuahua Health

The Boston Terrier Chihuahua mix doesn't appear to have many health concerns, and of those that may occur there seems to be nearly none that are serious. The hybrid vigor that happens when two purebreds are mated may be responsible for helping to generally eliminate the weepy eyes that Chihuahuas often possess, however, and the one serious issue can be heart problems. Otherwise, about all you need to watch out for are eye complications, allergies, deafness and joint ailments.

The estimated lifespan of the Boston Terrier Chihuahua mix tends to average 12 to 15 years.

  • Deafness
  • Heart Problems
  • Luxating Patella
