Teddy Roosevelt Terrier
TED-ee ROH-zuh-velt TAIR-ee-ur
Energetic, Loyal, Intelligent, Adaptable. A compact American ratting terrier named after the 26th president.
An adult Teddy Roosevelt Terrier weighs 8-25 lbs (male) or 8-25 lbs (female), needs 200-550 calories daily, and lives 14-16 yrs. As a small breed, every calorie and every ounce of body weight matters proportionally more. The breed's primary health watch is patellar luxation. All numbers below come from AKC breed standards and NRC 2006 veterinary nutrition formulas.
Nutrition and feeding
A typical adult Teddy Roosevelt Terrier needs 200 to 550 calories per day, depending on size within the breed's wide range. A smaller individual (12 lbs / 5.4 kg) needs around 320 kcal; a larger one (20 lbs / 9.1 kg) roughly 450 kcal. These estimates use the vet-standard RER/MER formula.

Health profile
The Teddy Roosevelt Terrier is generally a healthy, hardy breed. As a relatively recent AKC addition (January 2026), long-term breed health studies are limited, but the breed has a solid health reputation from its Rat Terrier lineage. Life expectancy is 14 to 16 years.
Exercise and activity
Bred to hunt vermin, the Teddy Roosevelt Terrier has substantial exercise needs for its size. At least 45-60 minutes of daily activity, including walks, play, and mental stimulation. They excel at agility and obedience training. A bored Teddy Roosevelt Terrier will dig, bark, and find creative ways to entertain itself at your expense.
Care and traits
Teddy Roosevelt Terriers have a short, dense, smooth coat. Origin: United States, developed from the Rat Terrier line.
The breed was split from the Rat Terrier by the UKC in 1999, distinguished by its shorter legs and stockier build. Named after President Theodore Roosevelt, who reportedly kept similar terriers. Their short coat needs minimal grooming; weekly brushing and occasional bathing is sufficient. They adapt well to both apartment and rural living if exercise needs are met.
Grooming needs are minimal. A weekly brushing to remove loose hair and distribute skin oils is sufficient for most Teddy Roosevelt Terriers. Bathing is only needed when the dog is noticeably dirty or smelly.
Their small size makes them suitable for apartment living, but they still need daily outdoor exposure and socialization. Small dogs are vulnerable to injury from rough handling, falls from furniture, and confrontations with larger animals. Supervision around young children is essential.
The Teddy Roosevelt Terrier responds exceptionally well to positive reinforcement training. Their eagerness to learn makes them suitable for advanced obedience, trick training, and competitive sports. Start training early and keep sessions varied to maintain their interest.

Frequently asked questions
Daily needs range from 200 to 550 calories depending on the dog's size (the breed ranges from 8 to 25 lbs) and activity level. These terriers are active by nature and burn calories efficiently. An active 15-pound Teddy Roosevelt Terrier typically needs around 380 kcal. Adjust upward if your dog gets heavy exercise or works as a ratter, and downward for more sedentary indoor life.
The breed standard calls for 8-25 lbs (3.6-11.3 kg) regardless of sex.6-11.3 kg) for both sexes, which is a wide range. Your individual dog's ideal weight depends on their frame size. The key assessment is body condition: you should feel ribs easily with light pressure, see a defined waist from above, and notice an abdominal tuck from the side.
Veterinarians most commonly identify patellar luxation in Teddy Roosevelt Terriers. The primary physical differences are shorter legs and a stockier, more compact build compared to the Rat Terrier's leggier frame. Temperament is similar: both are intelligent, energetic ratting dogs with strong prey drive and loyalty to their families.
Budget 45 to 60 minutes of exercise daily for a Teddy Roosevelt Terrier. These are working terriers bred to hunt vermin, and they retain that drive and energy. Walks alone are not enough; include fetch, tug, agility practice, or nose work games. Mental stimulation is just as important as physical exercise for this intelligent breed. Without both, expect digging, barking, and creative mischief.
