Rat Terriers are American farm dogs, developed in the late 1800s and early 1900s from English terriers and feists, with Whippet and Beagle blood added later for speed and scenting. Families kept them to clear barns of rats and hunt squirrels. They come in miniature and standard sizes, usually 10 to 25 pounds, with a short, smooth coat that is always pied with white.
Many Rat Terriers are cheerful, affectionate and more biddable than other terriers, but they keep a strong prey drive and a love of digging. In Garland, where coyotes have been spotted in residential yards, a secure fence and a leash on walks matter. Shedding is moderate, and every dog's personality is a little different.
