The Rat Terrier is an American farm dog from the late 1800s and early 1900s, developed from English terriers and feists, with Whippet speed and Beagle scenting added later. Families kept them to clear barns of rats and to hunt squirrels. They come in miniature and standard sizes, usually 10 to 25 pounds, with a short, smooth coat that always includes 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 Muskegon, squirrels and birds in city parks will tempt them, so a leash is the right tool on walks. Dogs vary, but a well-matched Rat Terrier is a small, long-lived companion, often 12 to 18 years.
