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 added later. Families kept them to clear barns of rats and hunt squirrels. The coat is short, smooth and always pied with white, and the breed comes in miniature and standard sizes, usually between 10 and 25 pounds.
Many Rat Terriers are cheerful, affectionate and eager to stay close to their people, and they tend to be more biddable than other terriers. They also have real energy, quick reflexes and a strong prey drive, and many like to dig. In Sarasota, that means daily activity, secure fencing and a short, warm-weather walking schedule, but each dog's personality varies.
