Smooth fox terrier is a small, alert dog originally bred for use in fox hunts. A smooth fox terrier stands about 15 inches (38 centimeters) tall and weighs about 18 pounds (8 kilograms). The dog is white in color with patches of black or tan, or both black and tan. Its coat is smoother than that of the wire fox terrier. A smooth fox terrier has legs well suited for running. The quick action of its upright tail gives the dog a lively look. The breed was developed in southern England in the mid-1800’s. The dog has good eyesight and a keen sense of smell. It is also fast and strong for its size. The dog makes an excellent companion for children or adults.
