The Brat is a hybrid mix between the Boston Terrier and the Rat Terrier. Not much is known on this hybrid outside of the parent breeds. The Rat Terrier was only recognized as a breed in 2013. Both parents are athletic, compact, and small sized and the Rat Terrier comes in miniature or standard sizes. The Brat will resemble both parent breeds well. Both parent breeds belong to the Terrier family and were originally bred for vermin control and as companion dogs. Today, the Brat is considered a companion designer dog.

Brat Breed History

The Brat is hybrid of two Terrier dogs, the Boston Terrier and the Rat Terrier. Its history is unknown at this time, and the hybrid is a modern dog, only rising in the last few years. This mix is a designer hybrid bred as a companion. To better understand the history of your Brat, you must look to the history of the parent breeds. The Boston Terrier is of the Terrier and Bulldog families, having risen from the experimental cross-breeding between now extinct English White Terriers, Old English Bulldogs, and French Bulldogs during the late 1800s. Unsure of what to call this young breed of dog, fanciers attempted to associate them with the Bull and Terrier groups but faced resistance from the well-established breeds in the respective group. Finally, the Boston Terrier was decided on to pay homage to the region where the breed was developed, and American Kennel Club recognized the breed in 1893 as one of the first non-sporting breeds and was the first of the ten “made-in-America” breeds to be recognized. The All-American breed was chosen for the bicentennial dog and is the official dog of Massachusetts. The Rat Terrier is a long-bred mix of many Terriers including the Fox Terrier, the Bull Terrier, the Manchester Terrier, and the Old English White Terrier crossbred with Whippets, Greyhounds, and even Beagles to increase the speed and scenting abilities. The Rat Terrier is a small farm dog and was bred to hunt small vermin, including fast jack rabbits. The breed was not recognized by the American Kennel Club until 2013, despite having a long-documented history most likely due to its sorted crossbreeds. President Theodore Roosevelt kept a Rat Terrier, and some say he is credited with naming it for its rat control at the White House. A Rat Terrier also appeared alongside child actress, Shirley Temple, in the film, “The Little Colonel."

Brat Breed Appearance

The Brat is a hybrid between the Boston Terrier and the Rat Terrier and will often have distinctive characteristics of both breeds. Both parent breeds are of the Terrier family and are small dogs. This hybrid often resembles the color and markings of a Boston Terrier in black and white or sable and white. The head of this hybrid is square-like but with a softness to it and the muzzle is not as short as a Boston Terrier yet not as long as a Rat Terrier’s muzzle, displaying both parental breed facial traits. Underbites are common on the Brat and may require dental work to correct. The ears are triangular and stand half-pricked with excellent mobility. The body is compact and muscular, and the tail is level with the back and whip-like. With no one parent breed stronger in appearance, this hybrid is a solid mix between his parents.

Brat Breed Maintenance

The Brat is a mix between two Terriers with differing levels of shedding. The Boston Terrier is not known to shed a lot and has fine hair whereas the Rat Terrier is slightly coarser and can shed a moderate amount. Weekly grooming will help remove the dead and loose hair from your Brat’s coat and help keep his coat and skin healthy. Both parent breeds may suffer from dermatitis so frequent bathing is not suggested. Brushing will also help remove dirt and distribute natural oils. The Brat may inherit a underbite from its Boston Terrier parent and requires frequent teeth cleaning. Early and often teeth cleaning will help acquaint your Brat with this process and keep his mouth and gums healthy.

Brat Activity Requirements

The Brat, despite his name, is a sweet, cheerful hybrid who does not bark often. They are less aggressive than the Rat Terrier and enjoy a good lap to cuddle in. This hybrid is relatively friendly with strangers as both parents are open and cheerful around people. The size of this hybrid does not make it ideal for small children who may accidentally hurt the dog, but this hybrid does very well with kids who can respect its size. The Rat Terrier parent can make the hybrid slightly more aggressive towards other dogs and small pets, like cats but the Boston Terrier, who gets along well with other pets, evens this character trait out so that without proper socialization, your Brat can live in harmony with other pets. The Brat is an intelligent mix but can be slightly stubborn due to the Rat Terrier lineage. However, with early and consistent training as well as positive companionship, your Brat is eager to please and will respond positively to your efforts. Early socialization with other people, pets, and places will also help prevent your Brat from developing behavioral issues. The Brat is a high energy dog that requires daily exercise. The Brat is a high-intensity hybrid but does not require long periods of exercise and he will settle down quickly in your lap once playtime is over.

I adopted my Brat from a rescue shelter, 8.5 yrs ago, when he was estimated to be about 3 yrs. He had sadly been abused & found abandon. He had been in the shelter (and foster care) for a long 1.5 yrs. He was extremely shy & timid, so while cute, he wasn't catching the attention of families. He was already housebroken & walked well on leash. It took him 4 days to stop hiding in my house, but once he came out to trust me, he has not left my side for a moment!!! I can get him to run around (and he runs graceful and FAST!), but he doesn't care for toys. It's like he's too smart for them (if I can't eat it, why chew on it?? Lol). He's obsessed with treats, licking & grooming himself, cuddling & kissing me. He's my snuggle buddy!! He has a unique underbite that's his most endearing quality; it's makes him smile all the time :) People love it.

My Brat is very excitable and isn’t a barker at everything, but he certainly isn’t quiet. Very easy to train. Not for a first time dog owner as they are high maintenance. They require a lot of toy time and being able to run. Bathtime is a breeze and the coat is nice. I’ve not noticed any shedding. HIGHLY intelligent. Is nippy and doesn’t get along with other dogs. Dog training is a must!

he’s the best and cutest pup! Loves his people more than anything and always wants to be snuggled up with us under the blankets. Has some itching and licking problems and barks way too much. Gets along with every human and animal but can be a little overwhelming when you first meet him bc he jumps a lot w excitement. He’s also able to jump onto a counter without a running start. But he’s the cutest thing and melts all the hearts!

She is very smart. She is territorial. She is really fast. She loves to snuggle and nap with me. She is very curious and loves sniffing out intruders in our yard, has an instinct to chase and tree squirrels. She is playful. She likes everyone in our house, but she shows favoritism to me.

Very energetic,but nervous with other pets. I try for her to get along with pets but she sounds like maybe its hard for her to get to know .loves people everywhere i take her shes happy. Knows most tricks in her nine months . Understands a trick in one week. But stubborn to stay in a training crate without her whinning. So shes attached to her owner but will hope to break from her neediness. Highly intelligent. Needs alot of socialization,training once a week maynot be enough for her to like other animals. hopefully, petco or petsmart or a training facility does more than week. I love my dog but alot of maintenance when it comes to attention.

Like the Boston, she follows me everywhere I go and sticks real close. Like the Rat she can be feisty and will dig for moles. She has the quietest sweetest howl I have ever heard (after I encouraged her howl). She does love to bark at other dogs.

Zo is the BEST dog I have ever had the fortune of meeting. She's very sensitive & sweet - this biography is pretty accurate. She is a jovial and social dog, she has always gotten along with other animals & people. Does well with children and has inspired other family members to look for a dog as well. Pretty quiet but purposeful- she likes to have a backyard and will "patrol" for intruders. She does tricks with patient & consistent training. Sometimes she will get a stubborn look in her eye- she's most responsive to positive food reinforcement but will be hurt by negative/pushy behavior. In times when we didn't have a large backyard, she regularly wants (coughDEMANDS) long walks. Despite her calm demeanor she has enough energy for long walks, hikes, runs, and genuinely enjoys exploring outside. She likes being the center of attention & absolutely loves cuddles and snuggling up with her fam.

Gus is very affectionate and loyal. He gets along well with other dogs, including our two additional dogs, though he’s very vocal during playtime which is an issue with more timid or aggressive dogs. We lose him around the house sometimes, only to find him burrowed under a blanket or pile of clothes; and if the sun is shining through the window, then you’re guaranteed to find him perched wherever he can soak in some rays. He’s a real people person, and absolute attention fiend. Any time we have guests, Gus will bring them his favorite toys. One really nice thing is we don’t have to worry about him getting out. On more than one occasion, I’ve left the garage doors open while I’m taking the trash out, and I’ll find him just sitting in the driveway taking in the view. He has what we call his “baby,” which is just a stuffed animal that he doesn’t treat like other toys. He soothes on it a lot, and when it’s time to calm down it’s his go-to object for comfort. Gus has some issues pulling when he goes for walks, but his penchant for picking up tricks and commands incredibly quickly leads me to believe I may have improperly leash trained him. He’s very food driven, which helps with training, but can be an issue when other dogs are eating around him. He was crated for the first year we had him, mostly when we left the house. But in the last two years we moved to letting him roam with his brother and sister while we’re away. We’ve had no issues aside from the occasional accident. To summarize, just a fantastic breed. Great energy balance, and easy to train. Gets along well with other dogs, as well as people. Fun quirks that make them so unique.
