Fell terriers are the long-legged working terriers of northern England's hill country, where shepherds needed dogs that could follow foxes into rock crevices. The Patterdale, named for a Lake District village, is the best-known strain in the US, and listings often use both names for the same small black, red or chocolate terrier. Coats can be smooth, broken or rough.
Patterdales were bred for gameness rather than looks, so many have intense prey drive, plenty of energy and a strong will. The UKC warns they aren't for the average pet owner. In Austin, that means a secure yard, a leash near wildlife and reward-based training. With those in place, many are affectionate, funny companions for active people.
