Throughout its history, the Welsh Terrier has been known by a number of names: the Black-and-Tan Wire Haired Terrier, the Old English Terrier and, at one point, the Old Reddish-Black Wirehaired Terrier, before the simple "Welsh Terrier" was settled on.
They look like a small version of an Airedale Terrier. They have a generally square appearance. Their head is rectangular with front-folding ears, bushy eyebrows, beard and moustache. Their double coat has a soft inner layer and a harsh outer layer and is normally black and tan or grizzle with a black jacket marking over the back.
They were bred for going out with packs of hounds and driving prey such as badger, fox and otter out of dens.
The Welsh Terrier is an intelligent, affectionate and playful dog. Like all Terriers, they have a stubborn streak but they are loving and loyal. They like to swim and dig. They are usually patient with children but need to be socialized well with strangers, dogs and other animals. Although not, perhaps, as high energy level than some of the other hunting terrier breeds, the Welsh Terrier still has plenty of energy and loves to run but care must be taken as they love to chase, too.
They shed little but need to be brushed and combed regularly and have their coat stripped about three times a year. They can be prone to eye problems and skin irritations.
