Fell terrier is the old name for the tough, long-legged working terriers of northern England's hill country, where shepherds needed dogs that could follow foxes into rock crevices too deep to dig. The Patterdale Terrier, named for a village in the Lake District, is the best-known strain of that type, refined in the twentieth century by huntsman Cyril Breay and recognized by the UKC in 1995. Shelter listings often use the two names for the same small, narrow-chested, black, red or chocolate terrier.
Patterdales were bred for courage and gameness, not looks, and many keep an intense prey drive, high energy and a strong will. Even the UKC standard warns they are not for the average pet owner. With plenty of exercise, secure fencing and patient, reward-based training, many become affectionate, funny companions for experienced, active people who enjoy a true working terrier.
