|wirehaired fox terrier|
There are two varieties of English fox terriers: the smooth-aired and the wirehaired. Both types have a hard wiry coat, which is primarily white with tan or black and tan markings. However, the coat of the smooth-aired fox terrier is shorter and flatter than that of the wirehaired. English fox terriers cannot be raised in packs but must have separate kennels because they fight with one another.
American fox terriers are among the most popular of purebred dogs, particularly in the midwester United States, where they are the most familiar house dog. They range in weight from 3 to 20 pounds. Their coat is shorter and smoother than that of the English fox terrier, and they have a dainty appearence. They also tend to be more affectionate and less inclined to fight than the English breed.
