While the Great Pyrenees is extra-large and intimidating, the Pyrenean Shepherd is much smaller and faster, more like a soccer player than a goalie. There are two distinct types of the Pyrenean Shepherd: the smooth-faced and the rough-faced. Rough-faced type has long or medium-length hair that's flat or slightly wavy, with a harsh texture. The hair on the end of the muzzle and chin is naturally short, with longer, swept-back hair on the sides of the muzzle and cheeks, giving the dog a windblown look. The smooth-faced type has a face covered with short, fine hairs. On the sides of the head, the hair is somewhat longer, creating a modest ruff. The fine, soft hair on the body reaches a maximum length of two inches along the back and three inches for the ruff and culottes (the hair covering the rear end and back legs).
It is unknown when this breed originated, but it was developed as a working companion for the Great Pyrenees; it would herd flocks of sheep while the Great Pyrenees stood guard over them. The Pyrenean Shepherd came to North America in the 19th century to be used as herders. They made names for themselves by serving alongside soldiers during World War I as guard dogs, couriers, and search-and-rescue assistants. Pyrenean Shepherd advocates established the breed standards in the 1970s. The breed was recognized by the AKC in 2009. Today, this is a companion dog and a working dog who particularly excels at search and rescue work.
