The Rat Terrier is an American farm dog, developed in the late 1800s and early 1900s from English terriers and feists, with Whippet and Beagle added later for speed and scenting. Farm families kept them to clear barns of rats and hunt squirrels. The breed comes in miniature and standard sizes, always with white in a pied coat, and the AKC fully recognized it in 2010.
Many Rat Terriers are cheerful, affectionate and eager to stay close to their people, and they're often more biddable than other terriers. They also have strong prey drive, quick reflexes and a love of digging. In Brooklyn, that means a dog that notices every pigeon and squirrel on the block and does best with daily activity. Dogs vary, so a Rat Terrier's own personality matters most.
