This breed was developed at the border between England and Scotland and received this name in 1880. Until then, it was called Coqetdale terrier. It is supposed to be the result of the crossbreedings between the old English Terrier and the Dandie Dinmont Terriers and the Bedlington Terrier. It has the needed resistance to keep up with other greyhounds while hunting and it is small enough to fit in a fox hole.
It is a small-sized, robust dog, with a long, strong, narrow body. The head is not like the other terriers' but more like an otter's, it is wide, with a short muzzle, a black nose, with whiskers and a beard. The eyes are medium-sized, dark brown and shaded by well-defined eyebrows. The ears are small, V-shaped, half folded towards the front. The tail is short, thicker at the base and pointed at the tip, carried high but not on its back. The fur is double-layered with short, thick, fluff and a thick and wiry outer layer. It can be: red, grey, straw-yellow, with grey patches or blue with brown.
It is a smart, brave, active, lively, very dynamic and strong dog, sometimes a little stubborn. It is devoted to its master, it is affectionate and patient with children. Socialized from an early age with other dogs and other household animals, it will have no problems. The same goes with strangers.
This dog's fur needs weekly brushing and trimming once a year to remove excess hair. It will never be cut.
It is a dog resistant to weather changes, which loves exercise and life in the open , but can adapt to life in a flat, in which case it will not be so dynamic and lively even if it is taken out for walks daily, as when it can move and run freely in a big space because of its high level of activity. It needs socialization and training.
This dog is easy to train because it is intelligent and learns quickly. The training must be consistent, well-balanced, gentle, and done with pleasure. It loves exercise and has a zest for life. It likes sports like flyball or agility competitions.
It's a dog used to hunt small wild animals and also as a pet.
