Originally bred to work on farms, the rat terrier is a small dog with high energy levels, high exercise needs, and a strong propensity to hunt and chase. Sometimes known as a rattie, this breed has a muscular, compact, and well-proportioned body with perky ears and an alert face that's always ready for action. Although rat terriers are born hunters—and make excellent watchdogs—they can be loving, affectionate, and loyal to their family members. With the proper training and socialization, they can also be friendly with strangers and other medium-size to larger pets.

Characteristics of the Rat Terrier
Rat terriers are ideal for active families with a large, fenced-in space to run around and exercise excess energy. Like many smaller breeds, rat terriers can become destructive when they're bored. It's also important to note that rat terriers have extremely strong prey drives, so they shouldn't be allowed to romp off-leash in open spaces where they can meet up with small animals.

History of the Rat Terrier
An American breed that was developed by breeding the fox terrier, bull terrier, Manchester terrier, and old English white terrier—among others—the rat terrier was originally bred to catch prey and hunt pests, such as rats, on farms, which is how they got their name.
Throughout the 1910s and 1920s, rat terrier breeders worked to propagate certain skills, resulting in several new lines in the breed. In the Midwest, rat terriers were bred with whippets and Italian greyhounds to produce quick dogs that could help control jackrabbit populations. In Central and Southwest America, they were bred with beagles to improve upon their hunting skills and to create more pack-oriented dogs. In the 1920s, toy fox terriers that were too large for their breeding programs were bred with rat terriers, resulting in toy-sized, or miniature, rat terriers.
The rat terrier was common on American farms, but populations began to decline in the 1940s and 1950s when farmers began to use poison to control pests and vermin. A small number of breeders maintained the breed until they came back into popularity in the 1970s.
Two other types of rat terriers were developed during this time, including the decker rat terrier and the hairless rat terrier. The decker rat terrier is a slightly larger dog that excels in hunting and will retrieve from water, while the hairless rat terrier is a smaller, hairless dog that comes in miniature and standard sizes.
Rat Terrier Care
Although rat terriers are low-maintenance in terms of grooming, they are high maintenance in the exercise and training areas. It should come as no surprise that this working dog is highly energetic and has extensive and high daily exercise needs, which makes this dog an excellent pick for active families. Rat terriers also have a propensity to dig, so it's important to provide your rat with a designated digging spot in the backyard.
Because the rat terrier was bred as a working and hunting dog, it has very high energy levels and exercise needs. You can expect to exercise your rat terrier for at least 40 minutes each day—ideally, in a fenced-in space with room to run around. They are fast runners and high jumpers, so make sure the fence is 5 to 6 feet high. Rat terriers have a strong prey drive, so allowing them to play off-leash in an open space isn't recommended. If you don't have a fenced-in area for your rat terrier to run, be sure to take several, vigorous walks each day.
Like any breed, it's important to check your rat terrier's ears for debris or signs of infection weekly. If your dog's ears are red, inflamed, or smell funny, schedule a visit with your vet ASAP—these may be signs of injury or infection. If you notice a waxy build-up in your dog's ears, gently clean it with a cotton cloth. Avoid using cotton swabs, as they can damage the delicate inner-ear structures.
Dental hygiene is also extremely important when it comes to caring for your dog. Daily brushing is ideal, but brushing at least once per week can help protect your dog against dental and oral disease. Dental treats are fine in moderation, but shouldn't be the only method of dental care.
You can expect to brush your rat terrier only once per week with a rubber mitt or soft brush to remove loose hair and debris. Because they have very short, dense, smooth coats, you can bathe your dog on an as-needed basis. It's important to note that this breed experiences heavier shedding during the fall, spring, and heat cycles.
Like many terriers, the rat terrier is highly intelligent and can be extremely stubborn. What's more, this breed can become destructive when they're bored or unstimulated. Training and obedience may be challenging but it's vital for proper behavior and socialization. Keep training interesting—and keep your rat engaged—by incorporating games and rewards. If your rat terrier becomes distracted or you feel your training methods aren't working, try another technique.
Common Health Problems
Rat terriers are generally healthy dogs, but like all breeds, may be susceptible to certain health conditions. There's no guarantee your rat terrier will—or won't—develop these conditions, but it's important to know the signs and symptoms should they arise in your dog.
Some health problems that are commonly seen in rat terriers include:
- Incorrect bites: A slightly deformed jaw bone can result in an incorrect, or misaligned, bite. There are three types of incorrect bites, which are all seen in rat terriers: an overshot bite; an undershot bite; and wry mouth, or a twisting of the mouth. If your rat terrier doesn't grow out of her misaligned bite after 10 months, it's unlikely she ever will. Surgery may be performed to correct serious misaligned bites that interfere with chewing or swallowing.
- Demodectic mange: A condition caused by demodex mites, this condition can affect rat terriers with suppressed or weakened immune systems. Look for signs like redness, patchiness, or balding on the head, neck, or front legs.
- Allergies: A condition that can be found in all breeds, your dog can develop food, contact, or airborne allergies. Treatment depends on your dog's specific allergy and reaction.
If you're worried about your rat terrier's health, talk to your vet about simple ways you can help him live a long, happy, healthy life.
Diet and Nutrition
Your rat terrier's diet will depend largely on her size, age, and activity levels, but you can expect to feed her between .25 cups (for dogs weighing 10 pounds or less) and 2 cups per day (for dogs weighing between 30 and 40 pounds) of high-protein, high-quality dog food.
Where to Adopt or Buy a Rat Terrier
Rat terriers may be an easy breed to find in your area. Check your local animal shelter for rat terriers, or rat terrier mixes. Websites like Petfinder.com make it easy to search shelters in your area by breed, size, sex, and more. If you have a hard time finding a rat in a shelter, look for rescue organizations in your area.
If you choose to buy a rat terrier from a breeder, be sure to do your research to ensure you're working with an ethical, responsible breeder. Ask lots of questions, like "Where are the puppies kept?" and "How many litters do you produce per year?" If possible, ask to visit the breeding site and to meet the litters' parents. Be on the lookout for signs of backyard breeding, like unsanitary conditions or unhealthy dogs.
Adopting a rat terrier can cost a few hundred dollars to cover the cost of care. Buying a purebred rat terrier from a breeder might cost you up to $2,000.

Could a rat terrier be a good apartment dog?
Although rat terriers can thrive in smaller spaces, like apartments or condos, those living in small spaces should remember that rats were bred to run—so they need at least 40 minutes of exercise each day—and they have a strong instinct to bark.
Would this breed be a good choice for a first-time dog owner?
Because a rat terrier is highly intelligent, it has a mind of its own—and may be difficult to train if you're a first-time dog owner. The dog isn't big on pleasing its human, which can be frustrating for a new dog owner. An experienced dog owner will know how to be firm but loving with a pet, which is what a rattie needs from an owner.
Are rat terriers good with other small animals in the house?
Since this breed inherently hunts down pests and vermin, it's highly advised that owners avoid bringing small animals into the home as pets, such as hamsters, guinea pigs, mice, or birds. This dog may even consider cats and kittens as prey. Even a well-trained rat terrier may forget its manners when it spots a squirrel so imagine if your rattie encounters a hamster ball rolling around under its nose!
Is a rat terrier and Teddy Roosevelt terrier the same type of dog?
There is some confusion between the rat terrier and Teddy terrier breeds. That's because there's an unfounded rumor that Teddy Roosevelt named the rat terrier when his dog eradicated vermin in the White House. It is not fully confirmed which type of terrier that he owned, however, the Teddy Roosevelt terrier pays homage to the dog-loving 26th President of the United States. Teddies have longer legs than rat terriers, otherwise, they are very similar in nature and physical characteristics.
