small-to-medium breed
Teddy Roosevelt Terrier
A low-set American hunting terrier - shorter in leg and heavier in bone than the Rat Terrier, registered as the same breed until the two were separated in the 1990s, and named for Theodore Roosevelt, whose family feist cleared vermin out of the White House. Teddies are affectionate, funny, intuitive and easy to teach. What costs is instinct: a prey drive that does not negotiate, serious digging, alert barking, and a chondrodystrophic build carrying real disc risk.
Pup Height
8-14 in
The standard sets height only: at least 8 in and not to exceed 14 in, measured to the highest point of the shoulder, the same range for both sexes and no weight figure given. The build is low-set and rectangular, roughly 7:10 height to length, with the leg from elbow to ground about a third of the height at the withers. The coat is short, dense and medium-hard to smooth, and whiskers are left untrimmed. Any bi-color or tri-color is allowed with no preference, but there must always be some white, of any size and anywhere on the dog, and ticking in the white is acceptable as long as white stays predominant. Ears are carried erect, semi-erect, tipped or button, and tails may be docked, a natural bob or a natural full tail. Merle pattern, absence of white, hanging or cropped ears, a wall eye and a wire, broken, long or curly coat are disqualifications.

What’s Life With This Pup Really Like?
Very high. Teddies follow their person from room to room and finish the evening under a blanket.
Very good. Sturdy, playful and patient with children who are gentle, though a small terrier and a toddler both need supervising.
Mixed. Non-sparring with other dogs by the standard and usually fine with a cat raised alongside them, but rodents, rabbits and birds are prey.
High. Pack instincts and a watchdog streak mean strange animals and visitors get announced.
High. A working terrier's engine on short legs, needing an hour of real activity rather than a stroll around the block.
Moderate. A short coat sheds steadily year-round, and a weekly curry brush catches most of the loose hair.
Very playful. The standard's own phrase is class clown, and a Teddy will chase, dig, tree a squirrel and then do something ridiculous.
Very low. A tidy, dry-mouthed dog.
Very good. Quick, intuitive and eager to please, and the standard itself asks for a dog trained without a heavy hand.
Strong. Alert, protective for the size and quick to sound off, though 20 pounds of terrier limits what follows the warning.
Low. A weekly brush, an occasional bath, and regular nail and tooth care.
Good. Apartments, travel and changes of routine are fine with enough exercise, but long days alone and a weak fence are not.
Lifestyle fit
Could This Be Your Best Breed?
A Teddy Roosevelt Terrier does well in an apartment when the walks happen and better with a fenced yard, and suits an owner who wants an active small dog and will teach a quiet cue early. This is a cheap dog to run at $1,100 to $2,000 a year and a long-lived one at fourteen to sixteen years. Anyone with rabbits, rats or birds in the house has already ruled the breed out.
Living Space
An apartment works when the walks happen, and a securely fenced yard is better. Teddy Roosevelt Terriers settle indoors once the day has been busy, but a bored one digs, squeezes through gaps and announces every noise in the hallway, so walk the fence line before bringing a puppy home.
Pup Experience
A fair choice for a first-time owner who wants an active small dog and has read up on terriers. The standard asks for a dog that trains without a heavy hand, and that is what most Teddies are - quick, sensitive and genuinely willing. The work is in the digging, the noise and a prey drive that does not negotiate.
Daily Pup Time
About an hour a day of walks, chase games and nose work, plus short training sessions to keep a busy mind occupied. Grooming takes a few minutes a week.
Allergies & Coat
The Teddy Roosevelt Terrier scores 4/10 for shedding and 1/10 for drooling. No dog is truly hypoallergenic. The allergens come from dander and saliva, and a dog that sheds this much will leave plenty of hair behind - especially on your furniture, floors, and clothes.
Quirks & challenges
The Not-So-Easy Stuff
Prey Drive That Stays On
Bred to catch rats and tree squirrels, and the instinct is fully intact. Pet rodents, rabbits and birds are not safe in the same house, and recall fails the second something small bolts.
Digging
Short legs move a surprising amount of dirt. A bored Teddy will open up a flower bed or tunnel under a gate, so provide a digging box and check the fence line where the ground is soft.
Alert Barking
A watchdog instinct written into the standard, aimed at strange animals and anyone at the door. Teach a quiet cue in the first months rather than arguing with the habit later.
Reserved With Strangers
Caution around new people is normal in the breed and the standard says so. Steady early socialization is what keeps a reserved dog confident rather than nervy.
Long Back, Short Legs
The short legs come with a chondrodystrophic build, which raises the odds of a disc injury later on. Keep them lean, discourage repeat leaps off the back of the couch, and put a ramp where the jumping happens.
Needs Company and a Job
Bred to live with the family, and poor at long days alone, kenneling or life tied out. Under-occupied, a Teddy invents work - excavation, barking and counter patrol.

Health Risks
Conditions this breed is prone to.
The fibers holding the lens break down and the lens slips out of place, which is painful and a fast route to glaucoma and blindness without emergency treatment. The ADAMTS17 mutation behind the disease has a DNA test, and PLL sits on the breed's recommended health screening, so ask for both parents' results.
The kneecap slips out of its groove, showing up as a skipping stride or a hind leg carried for a few steps. Mild cases are managed with weight control and muscle; severe ones need surgery. A patella evaluation is part of the breed's recommended screening.
The short legs come with a chondrodystrophic build, and the FGF4 retrogene associated with it (CDDY) also raises the risk of intervertebral disc herniation. A DNA test exists and sits on the breed's recommended list alongside the eye, knee and cardiac checks. Sudden back pain, a wobbly back end or refusing to jump is an urgent vet visit, and surgery runs into the thousands.
A cardiac exam is on the breed's recommended screening list, and mitral valve disease is a common late-life problem in small dogs. A murmur caught early is usually managed with medication for years.
Environmental and food allergies run through the Rat Terrier family, showing as itching, paw licking, ear infections and red skin. They are managed rather than cured, with diet work, medication or bathing routines.
Small jaws crowd teeth and build tartar quickly, and a bite that falls short of the scissor the standard asks for adds to the problem. Daily brushing and regular dental checks head off extractions later.
Insurance & Health Coverage
A long-lived small dog, so a policy started for a puppy may need to run sixteen years or more. Check how the premium climbs with age, and what happens to a condition once you have claimed for it, because both matter more here than the first year's price.
The claims to plan for sit in the eyes, the knees and the back. Lens luxation is an emergency that costs thousands and can still cost the eye when treatment is slow, patella surgery lands in the same range, and disc surgery on a chondrodystrophic dog is the big one - often several thousand dollars per episode.
The inherited side is not insurable at all. PLL and the chondrodystrophy marker both have DNA tests, no policy covers a congenital condition, and both parents' results are the only real protection. Allergies are the quiet version of the same problem: once itching or ear infections are in the record, most insurers treat them as pre-existing, so cover taken out while the record is clean is worth the most.

The Daily Routine
Grooming
A short, dense coat with a sheen that asks for almost nothing - a weekly going-over with a rubber curry brush lifts the loose hair, and a bath every month or two is plenty. Leave the whiskers alone, since the standard wants them untrimmed. The routine that actually matters is nails, ears and teeth, which need more attention than the coat ever will.
Exercise
About an hour a day, and the nose matters as much as the legs. Flirt poles, hide-and-seek, scent games, barn hunt and agility all suit them better than a plain walk does. Stay on a leash or a long line outside a fenced area, because the prey drive beats the recall every time.
Food & Weight
Measure meals and count the training treats. Extra weight on a long back and short legs loads the spine and the knees, which are the two places this breed can least afford the strain, and a lean Teddy with a visible waist is the goal. Puzzle feeders slow a fast eater down and give a busy brain something to do.

If This Isn’t Quite the One
Rat Terrier
The breed they were registered with until the 1990s, when the short-legged Type B dogs were separated out. Rat Terriers stand taller on longer legs with a narrower head and lighter bone; the Teddy is low-set, broader in skull, heavier built, and carries the disc risk that comes with short legs.
American Hairless Terrier
Another breed drawn out of Rat Terrier stock, with the same bright, busy, affectionate character on normal-length legs. The American Hairless Terrier trades brushing and shedding for sunscreen, sweaters and a skin care routine.
Smooth Fox Terrier
One of the ancestors behind both breeds, with the same short coat and ratting history on a leggy, square frame. Smooth Fox Terriers are bolder, more argumentative with other dogs and less inclined to take direction.
Jack Russell Terrier
A comparable small hunting terrier with considerably more engine. Jack Russells are more intense and more independent; Teddies are calmer indoors and easier to talk out of an idea.
