Breed History
The Rat Terrier is an American breed developed from crosses of Smooth Fox Terriers, Manchester Terriers, Bull Terriers, Whippets, Italian Greyhounds, and Beagles. They were the quintessential American farm dog from the early 1900s to the 1950s, serving as ratters, squirrel dogs, and general-purpose farm companions. President Theodore Roosevelt is often credited with naming the breed after his own Rat Terrier successfully cleared the White House of a rat infestation. The AKC recognized the breed in 2013.

- Intelligent & Trainable: Rat Terriers are smart, quick-learning dogs that enjoy training and new challenges.
- Lively & Playful: They are active, playful dogs with a cheerful, fun-loving nature.
- Alert & Watchful: They are keen watchdogs that alert to anything unexpected in their environment.
- Friendly & Social: Unlike some terrier breeds, Rat Terriers are generally friendly and sociable with people and other dogs.
Care
- Exercise: About 30 to 45 minutes of moderate daily exercise. Walks, play, agility, and barn hunt activities are ideal. They enjoy variety.
- Grooming: Their short, smooth coat needs only weekly brushing. Minimal grooming requirements.
- Diet: Feed a high-quality small-breed food in appropriate portions. They are generally good eaters that maintain healthy weight with proper nutrition.
- Health: Watch for patellar luxation, hip dysplasia, Legg-Calvé-Perthes disease, cardiac conditions, and allergies. Generally very healthy and long-lived.

When you talk to a breeder, you're not just asking “do you have available Rat Terrier puppies?” You're looking for a match in the process of rehoming a dog. As a prospective dog owner, you are assessing how predictable the dog's health, temperament, and long-term welfare will be and whether the breeder's practices reduce avoidable risk.
You should engage in a conversation about the following topics:
- Which health tests and genetic screening do you do specifically for Rat Terrier, and can I see the results?
- What do you do if a puppy develops a serious genetic condition? What contract, policies and support do you offer as a breeder?
- How are puppies raised from birth to 8+ weeks? Ask about socialization, philosophies on early neurological development, handling, and exposure.
The real cost of a dog isn't just the puppy price. After year one, the cost of a dog includes the predictable annual costs + the unpredictable “risk costs.” Your goal is to make the cost legible before you commit, as one of the top causes of surrendering a dog is not being able to afford the dog in later years.
To help you assess these costs, Paction has created the Ultimate Cost Calculator. You can also read an article written by a Paction breeder on why a prospective dog owner should focus on the ongoing costs of dog ownership and not “how much” the puppy costs.
Every dog breed has certain health issues that tend to occur more often, but what matters most is how predictable and preventable those risks are. For many breeds, common concerns include inherited conditions (such as orthopedic, eye, or cardiac issues) as well as lifestyle-related challenges like weight management, dental health, skin or ear problems, and anxiety.
Responsible breeders help reduce inherited risk through appropriate health testing, careful selection of breeding pairs, and transparency about family history.

As an owner, you play an equally important role. Consistent preventive veterinary care, proper exercise and enrichment, healthy nutrition, and early screening can significantly improve long-term health outcomes.
Whether a Rat Terrier is right for you depends less on the breed itself and more on how well its typical energy level, temperament, and care needs align with your daily life. Important factors include your schedule and activity level, living environment, household dynamics (such as children, other pets, or allergies), and tolerance for noise or independence. Long-term fit also comes down to maintenance like grooming, training needs, and how often you travel or rely on outside dog care.
