Boston Terriers may be small, but they bring a lively, expressive personality that easily fills a room.

Boston Terrier Origin
The Boston Terrier originated in mid-19th century Boston, Massachusetts, bred from a cross between an English Bulldog and a now-extinct White English Terrier. Initially known as Round Head Bull Terriers, these dogs were later refined into the affectionate, well-mannered companions we know today. With their distinctive tuxedo-like markings, Boston Terriers have earned the nickname ‘The American Gentleman’.
A Bigger Boston Terrier?
In the 1870s, the early Boston Terrier was a far cry from today’s compact companion-larger, more robust, and weighing up to 45 pounds. These dogs, sometimes called Old Boston Bulldogs, were primarily used as ratters, and though some accounts suggest they may have been involved in pit fighting, there’s little historical evidence of widespread dogfighting within the breed. Over time, selective breeding softened their temperament and reduced their size, transforming them into the affectionate, refined dogs we know today.
Boston Terrier Populatiry
The Boston Terrier was recognized by the AKC in 1893. Their popularity skyrocketed in the early 20th century-so much so that from 1900 to 1950, more Boston Terriers were registered with the AKC than any other breed. This was a remarkable rise for a dog that began as a 45-pound ratter in 1870s Boston. Through careful breeding, they transformed from rugged ‘Old Boston Bulldogs’ into the smaller, sweeter-natured companions we know today.
What about “RED” Boston Terriers?
Boston Terrier Coat Colors: Debunking Myths
1. “Red” Bostons (Liver/Seal Controversy)
Genetic Reality: So-called “red” Bostons are typically liver (brown) or seal (black with red undertones in sunlight).
Key Identifier: A true red-toned Boston will have a matching reddish-brown nose and paw pads (liver pigment), unlike seal Bostons, which retain black noses.
AKC Standard: Only black, brindle, or seal with white markings are accepted. “Red” (or liver) is not a breed-standard color.
2. Merle “Bostons” Are Not Purebred
Genetic Fact: Boston Terriers do not carry the merle gene. Merle coats in dogs marketed as Bostons indicate crossbreeding (e.g., with Chihuahuas or French Bulldogs).
Health Risks: Merle is linked to deafness and eye defects. Reputable breeders avoid it.
3. Rarity Claims = Red Flags
Marketing Tactics: Terms like “rare red” or “exotic merle” are often used to inflate prices. Purebred Bostons are common in standard colors.
Breeder Ethics: AKC-registered Bostons must adhere to strict color guidelines. Non-standard colors disqualify them from conformation.
According to FCI Breed Standard
the Boston Terrier can reach up to 17 inches in height and up to 25 pounds in weight. Accepted coat colors are:
“Brindle, seal, or black with white markings. Brindle is preferred only if all other qualities are equal. (Seal appears black except it has a red cast when viewed in the sun or bright light.)”
Boston Terrier’s are NOT Terrier’s
The Boston Terrier, despite its name, is not classified as a terrier by the AKC but belongs to the Non-Sporting Group-a distinction made in 1893 due to its unique lineage as a companion-focused cross between bulldogs and now-extinct white English terriers. While early breeders used “terrier” for marketing or historical ties, the breed’s gentle temperament and physical traits diverged from traditional terrier characteristics, leading to its reclassification. This refined grouping underscores the Boston’s true identity: a purpose-bred American gentleman, not a working terrier.

Are Boston Terriers Aggressive?
In this Same Research the Boston terrier ranks very low 100 out of 124 breeds in aggression towards their owners. They do, however, rank much higher in aggression towards other dogs, both familiar and unfamiliar. Essentially, this means when another dog is approaching their territory, toy, food etc. they may react by growling, bearing of teeth and in severe cases lunging or biting.

Boston Terrier Intelligence
In the Landmark Book entitled, “The Intelligence of Dogs”, professor Stanley Coren researched and documented the intelligence of over 130 different dog breeds. In his book, the Boston Terrier ranks 54th out of 138 breeds in working/obedience intelligence. Essentially this means they will learn new commands in 25 to 40 repetitions and obey first commands more than 50% of the time. This puts them in the “average working and obedience intelligence” category. In contrast, the most intelligent breeds will learn the same command in 5 repetitions or less and the least intelligent, 80-100 repetitions!
Boston Terrier “Air Management”: A Gassy Affair
Boston Terriers may be small, but their flat-faced (brachycephalic) design makes them world-class air swallowers-and what goes in must come out! Their notorious gassiness can clear a room in seconds, while their repertoire of snorts, snores, and reverse sneezes could rival a sound effects board. Though these noisy, sometimes stinky habits are usually harmless (and oddly endearing), smart owners use slow-feed bowls, probiotics, and elevated dishes to minimize the chaos. Just remember: if your Boston sounds like a kazoo band warming up, it’s probably normal-but when in doubt, check with your vet. (And maybe keep a candle handy!)

Boston Terrier Facts-Final Thoughts
Boston Terriers are a popular breed of dog known for their distinctive features and friendly nature. With their short coat, erect ears, and prominent eyes, they have a unique appearance that sets them apart from other breeds. These dogs are not only good family dogs but also excel in dog sports and agility training. They love playing games of fetch and are always up for some outdoor fun, although they may need extra protection in cold weather due to their short coat and extreme heat because they are brachycephalic dogs (short muzzle). The Boston Terrier breed does not need extensive grooming and, as with any breed, they require obedience training at an early age to grow into well-adjusted friendly dogs as adults.
