The Teddy Roosevelt Terrier is an American ratting dog that shares its personality traits, coat colors, and breed origin with the rat terrier. The dogs have a low-set, small to mid-sized body and muscular frame with a coat that can be many combinations of colors. However, their colors must include white to qualify for breed standards. They have distinctly shorter legs than their rat terrier cousins.
An energetic and active breed that has not forgotten its hunting dog origins, these dogs, often called “Teddies,” are loyal to their family and also make great pets in all kinds of homes, from country farms to city apartments. Overall, they have a positive temperament and function well in domestic households for a working dog.
3 Pros and Cons of Owning a Teddy Roosevelt Terrier
| Pros | Cons |
|---|---|
| Compatible with Other Dogs The Teddy Roosevelt Terrier generally gets along well with other dogs in the field or at home. While they can be very attached or possessive of their owners, they aren’t known for their belligerence towards other canines. | High Activity Levels While this trait can be as much of a positive as a negative, prospective owners should be prepared for frequent exercise. This breed needs lots of activity throughout its daily life and prefers variable activity that allows it to put its intelligence to work. |
| Energetic and Friendly These terriers may be small, but they have plenty of affection to share and energy to spare. This makes them endearing and exciting companions for individuals and families, especially when raised alongside children or other pets. | High Obesity Risk These dogs have a rather stout, broad, and muscular frame proportionate to their size. This means they accumulate weight relatively quickly and can have a hard time shedding excess fat, so owners need to monitor their weight gain carefully. |
| Easy to Train As hunting and working dogs, Teddies are also receptive to training and greatly benefit from it. Owners should take the time to instill verbal commands and maintain a basic daily structure at the very least. | Single Owner Oriented While these dogs have a positive reputation as sociable family dogs, they can become particularly attached to individuals. This isn’t a problem for single owners, but families should take care to encourage the dog to spend time and bond with everyone in the household. |
Evolution and Origins
Teddy Roosevelt Terriers have a complex ancestry that includes many terrier breeds originally brought to the Americas by European immigrants. Manchester terriers, bull terriers, Italian greyhounds, and beagles are among the breeds thought to contribute to their genetic makeup.
While President Theodore Roosevelt was not a known owner of the rat terrier or instrumental in the development of Teddy terriers, the breed was named in his honor when it was officially recognized by the United Kennel Club in 1999, and later by the American Kennel Club in 2026. The president was a known dog lover who admired several of the canines he kept during his time in the White House. He praised his dog Skip in a letter lauding the animal’s loyalty, friendly demeanor, and ability to control the building’s rodent population.

Size and Weight
Kennel Club guidelines for these terriers require a minimum height of 8 inches for a grown adult with a maximum of 14 inches. Appropriate length is usually determined as a ratio to height, with the ideal height to length ratio being 7:10. Some of the biggest Teddies weigh in at 25 pounds, but adults can also be as small as 8 pounds when fully grown. On average Teddies are 11.5 inches tall and weigh 17.5 lbs.
Common Health Issues
These terriers are considered a healthy breed and generally live to reach their expected lifespan of 14 to 16 years. Most health issues seen in the breed are similar to those in rat terriers, including skin allergies, bite misalignment, and a rare eye disorder called ectopia lentis. They can also suffer from various joint problems like subluxated patella and dysplasia of the hip or elbow.
Temperament
High intelligence is a defining characteristic of the breed, which makes them interesting companions and ones that require real engagement from owners. Their alert and intuitive nature goes along with strong protective instincts. They are generally tolerant of other pets in their own household and rarely engage in direct belligerent activities with other canines. These traits also make them a good fit for families with children, especially if they grow up around kids.
Teddies are very owner-oriented dogs, which is a defining feature of their personality. This temperament drives them to participate in just about any activity that they can when their family is involved. They are very eager to please and are prone to suffering from separation anxiety if left alone for long periods.

How to Take Care of Teddy Roosevelt Terriers
Owners of Teddy Roosevelt terriers should be prepared to spend a lot of time with them, whether they are mature adults or young puppies. Providing attention, exercise opportunities, and diligent weight management are all important for their overall well-being.
The Best Dog Food
High-quality food mixtures are recommended for these terriers to ensure good coat quality and overall health. Home-prepared meal plans should be supervised and affirmed by a veterinarian. These dogs do have a propensity for weight gain, so owners need to carefully manage their pet’s total calorie intake. Small, lean treats are also recommended for training exercises.
Some Teddy Roosevelt Terriers have sensitivities and allergies. Fortunately, owners have plenty of allergy-control dog foods to choose from.
Maintenance and Grooming
These terriers don’t require much in the way of grooming and maintenance, although they do go through periods of seasonal shedding. A soft brush or mitt should be used to groom their coat about once a week. Occasional bathing and nail trimming are also recommended, especially for younger dogs that are active outdoors. Owners should also consider brushing their dog’s teeth and cleaning excess wax from their ears to keep their pet in good health.

Training
Since Teddies are very eager to please their owners and are highly intelligent, training is usually quite easy. They respond well to verbal praise from their owners as well as the occasional treat to reinforce the right behavior. The breed is also known for its steadfastness and determination, which means they are unlikely to give up or become discouraged even if they don’t succeed right away. Balanced training that includes agility exercises, obedience, and other activities is recommended.
Exercise
Even though these terriers are small dogs with short legs, owners can easily tire themselves out before their pet is ready to give up. Teddies need a lot of physical exercise to get all the excess energy out of their system. Fetch games with balls or discs are a good way to run some of their exuberance out of their system. Hiking and swimming are also acceptable activities, although owners should ensure their dog has a safety harness and secure the leash to prevent accidents. These dogs should get about an hour of activity a day, and healthy adults should get 10 to 12 miles of walking each week.

Puppies
Teddy Roosevelt terrier puppies have many of the same special considerations as adults. They have high energy levels and need regular activity starting once they are steady on their feet. They also respond well to training at an early age, so owners should take advantage of this to instill basic obedience and attentiveness to verbal cues in the first few months of their life. Puppies should also be exposed to children, cats, and other dogs safely to encourage a positive attitude towards them in the future.

Teddy Roosevelt Terriers and Children
These terriers are generally considered good family dogs and safe to have around children. However, they can tend to bond with their primary owners, usually, the parents, who take them for walks, engage in training, and provide food. Parents of children should involve their children in pet care to ensure bonding with all family members.
Dogs Similar to Teddy Roosevelt Terriers
- Bull Terrier: Bull terriers are short, muscular, and activity-oriented, much like Teddies. However, they are much more independent-minded and can be harder to train.
- Beagle: Much like Teddy Roosevelt Terriers, beagles are loyal and intelligent companions that are comfortable inside and outside. Both are good family pets with a solid lifespan, but beagles can be more difficult to train.
