The Rat Terrier is an American farm dog, developed in the late 1800s and early 1900s from English terriers and feists, with Whippet speed and Beagle scenting ability added later. Farm families kept them to clear barns of rats and chase squirrels. The AKC fully recognized the breed in 2010, and it comes in miniature and standard sizes, always with white in a short, smooth, pied coat.
Many Rat Terriers are cheerful, devoted and more biddable than other terriers, but they still dig, chase and bark at anything that moves. In Henderson, that means secure fencing and training for quiet habits, since the city's code covers frequent barking that disturbs neighbors. Dogs vary, so a Rat Terrier's own history and socialization say more than any breed description.
