Best For

Energetic and playful, Rat Terriers want to be your bestie. These fast learners thrive in busy, active households with pet parents who can provide early socialization, daily training and lots of playtime. But don't worry, when it comes to their grooming needs, they're low-maintenance.

Rat Terrier Traits

Rat Terrier Temperament

Rat Terriers are a big personality in a compact body. Inquisitive and highly intelligent, these qualities work in their favor when it comes to puzzles and games that will provide seemingly endless entertainment.

When they’re given a job to do, however, things get serious. They give 100 percent whether they’re hunting vermin, running agility or having a training session. Because Rat Terrier dogs were bred to both function as a working dog and live with a family, they can master both equally.

These small-sized dogs are usually very friendly and tend to get along with kids and other dogs, but it’s important to remember that all dogs are individuals so this can differ from Rattie to Rattie. As long as your dog is properly socialized (aka introduced to different people and environments) from a young age, they’ll be a great companion for all the family, and a friend to anyone they meet. It’s also important to teach kids how to interact with dogs.

As their name implies, these dogs kind of have a thing for vermin. So you may want to rethink a Rat Terrier if you keep house with rats, mice, hamsters or birds unless you take precautions to keep them separated. The same goes for cats, but with early and deliberate introductions as Rat Terrier puppies, the two can definitely thrive together.

Rat Terriers are good watchdogs, so don’t be surprised if they bark when someone comes to the door. If you feel that it’s excessive, there are options to help you reduce your dog’s barking.

Overall, Rat Terriers are devoted to their people and they love to be included, so don’t leave them alone for too long or they will pine for you. Don’t forget that they still operate on instinct—no matter their training, your Rattie might still make the occasional, sudden lunge for a squirrel on your afternoon walk. They’re just doing what they were bred to do!

How to Care for a Rat Terrier

Rat Terriers are pretty low maintenance when it comes to their grooming needs, but when it comes to training, they need daily exercise and a pet parent who is as determined and dedicated as they are. They’re affectionate and love family life, and they are adaptable enough to be anything from apartment-dwellers to farm hands.

Rat Terrier Health

Rat Terriers have a decent life expectancy and can live 12-18 years. They tend to be a very healthy and active breed, but, like all dogs, they are prone to certain health problems. It’s good to know ahead of time what these concerns could be so you can look out for any tell-tale signs. 

  • Hip Dysplasia: This often-genetic condition can occur when the hip joints are loose, causing pain, cartilage loss and scar tissue if not addressed. Treatment options include weight management, physical therapy or surgery. 
  • Patellar Luxation: This causes the kneecap to dislocate, resulting in pain and loss of function. It can be genetic and treatment option include joint supplements, pain medication and, in severe cases, surgery.  
  • Legg-Calve-Perthes Disease: The hip joint is formed from the ball and socket. In Legg-Calve-Perthes disease, the ball, or top of the femur bone, starts to deteriorate, which can be very painful. Surgery is often the treatment of choice.  
  • Heart Disease: Heart problems can be common when raising a Rat Terrier into their senior years. Your veterinarian will want to monitor their heart for any concerns so that if there’s an issue with their heart or the heart valves that pump blood, these can be addressed. If your vet hears a heart murmur, they will likely refer you to a veterinary cardiologist for an echocardiogram (ultrasound of the heart) to determine the underlying cause.  
  • Eye Disease: Rat Terriers are prone to a certain disease called primary lens luxation that can lead to teary, red and/or cloudy looking eyes. Eventually, dogs can go blind. If you notice any of these signs or have concerns about your pet’s eyes or vision, please contact your vet immediately. 

Rat Terrier History

Rat Terriers earned their name through history by being experts at catching rats. They originated on American farms, where these little dogs were perfect for exterminating the vermin that could potentially wreak havoc on stored food needed for survival. In fact, they were specifically bred for this very task and in the 1910s and 1920s, they were the most common farm dog in the US.

The Rat Terrier dog breed comes from a mix of several different breed types, including the Smooth Fox Terrier, Manchester Terrier, Whippet, Italian Greyhound and Beagle. Farmers used different combinations of breeds to land on the traits they required for the job. For instance, Whippets and Italian Greyhounds were included for their speed and the Beagle for their superior hunting skills. An American original, it’s said Teddy Roosevelt is responsible for naming this breed.

As farmers started killing rats with poison, Rat Terriers became less popular until the 1990s when they started making a comeback. The Rattie was officially recognized by the American Kennel Club (AKC) in 2006.
