A true American farm dog, the Rat Terrier was developed in the late nineteenth and early twentieth centuries by crossing English terriers with feists, and later adding speed from Whippets and scenting ability from Beagles. Families kept these compact, smooth-coated dogs to clear barns of rats and hunt squirrels and other small game. The breed comes in miniature and standard sizes, always with white in its pied coat, and the AKC fully recognized it in 2010.
Many Rat Terriers are cheerful, affectionate and eager to be close to their people, often more biddable than other terriers. They still have strong prey drive, quick reflexes and plenty of energy, and they like to dig and explore. Adopters can expect a portable, long-lived companion that needs daily activity, secure fencing and supervision around small pets.
