Wirehaired Terrier is a coat description as much as a breed. It's a common alternate name for the Wire Fox Terrier, the English terrier developed to bolt foxes from dens and later made famous as Asta in The Thin Man and Snowy in Tintin. Shelters also use the label for wire-coated terrier mixes with Jack Russell, Border, Cairn or Schnauzer ancestry. Most weigh roughly 13 to 25 pounds and live 12 to 15 years.
Expect a bold, friendly, alert dog with classic terrier habits: barking, digging and chasing small animals. The dense, crisp coat sheds little but needs weekly brushing and stripping or clipping about every 6 to 8 weeks. Because most walks in West Chester happen on a leash along borough sidewalks, that busy mind needs puzzle toys and training games as much as miles. Ancestry varies, so the dog in front of you says more than the name on the listing.
