Fox Terrier usually means the Smooth Fox Terrier or the Wire Fox Terrier, two related breeds that share a build and a personality but differ in coat. Both came out of Britain, where they were developed to follow foxhunts and bolt foxes from their dens, and their mostly white coats kept hounds and riders from mistaking them for the quarry. Listings sometimes use the name loosely for terrier mixes, and the tiny Toy Fox Terrier is its own breed.
Expect a bold, quick, independent dog with a mind of its own, so training works best when it stays varied and patient. The Smooth's short coat needs little more than a weekly brushing, while the Wire sheds little but needs regular clipping or hand-stripping, which affects what you'll spend. In Modesto's dry climate, either coat copes fine with a quick brush after dusty outings.
