Take the quizBalanced, compactly built Rat Terriers are tough but elegant-looking. There are two size divisions: Miniatures stand 10 to 13 inches at the shoulder; standards are over 13 inches and as high as 18 inches. The smooth, shiny coat comes in varieties of pied patterns. (Pied, a word borrowed from the horseman’s lexicon, means “comparatively large patches of one or more colors in combination with white.”) These smoothly muscled exterminators are constructed for the efficient movement required for a long day’s work. An American original, with a breed name said to be coined by Teddy Roosevelt, the Rat Terrier is a compact, tough, smooth-coated exterminator dog. RTs come in two size varieties and are happy-go-lucky, playful, and portable companions.

Best For
Home & Lifestyle Fit
The Rat Terrier is built for an active lifestyle. Daily exercise isn't optional — expect at least 45–60 minutes of real activity, plus mental stimulation through training, puzzle toys, or dog sports. A house with a yard is ideal, though they can adapt to apartments if exercise needs are consistently met.
Day-to-Day Reality
Coat care is minimal: a quick brush and occasional bath keeps them looking their best. Shedding is average — manageable with regular brushing. This breed craves human company. Long days alone can lead to anxiety or destructive behavior, so a work-from-home setup or doggy daycare is worth planning for.
