Fell terrier is the old name for 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, refined by huntsman Cyril Breay and recognized by the UKC in 1995. Listings often use both names for the same small black, red or chocolate terrier, with a smooth, broken or rough coat.
Patterdales were bred for courage and gameness, so many keep a strong prey drive, high energy and a mind of their own. The UKC standard itself warns they aren't for the average pet owner. In Murfreesboro, where rain keeps yards muddy much of the year, expect some digging and wet-coat cleanup along with the charm. Reward-based training and daily exercise help a lot.
