Fox Terrier usually means the Smooth or the Wire, two close cousins from Britain that share a build and a personality but not a coat. They were developed to bolt foxes from their dens, which explains the mostly white coat and the fearless streak. Most weigh 15 to 19 pounds and live 12 to 15 years.
Expect a lively, funny, stubborn dog with a strong prey drive and a mind of its own. Training works best when it stays varied and patient. The Smooth's short coat takes a weekly brushing, while the Wire sheds little but needs clipping or hand-stripping. In San Antonio, that mix of energy and coat care shapes daily routines, from leash habits to summer heat, and every Fox Terrier varies.
