Fell terrier is the old name for the tough, long-legged working terriers of northern England's hill country, where shepherds needed small dogs that could follow foxes into rock crevices. The Patterdale, named for a Lake District village, is the best-known strain. The UKC recognized it in 1995, but the AKC doesn't, so listings often use "Patterdale" and "Fell" for the same small, narrow-chested black, red or chocolate dog.
Patterdales were developed for courage and gameness, not looks. Many keep an intense prey drive, high energy and a strong will, and the UKC standard itself calls them unsuitable for the average pet owner. In Shawnee's tree-lined neighborhoods, squirrels and rabbits are constant temptations, and coyotes live across the Johnson County suburbs, so a leash outside the fence matters. With exercise, patient reward-based training and a secure yard, many become funny, affectionate companions for active people.
