"Early historic and ethnographic accounts report the presence of two types of dogs (Canis familiaris) kept by the Makah and Coast Salish peoples of the south central Northwest Coast of Sorth America (southeastern Vancouver Island, northern Olympic Peninsula, the Gulf Islands, Puget Sound and the Fraser River Delta). These accounts describe a medium-sized, short-haired dog and a smaller, long-haired one. The small type or "wool" dog was reportedly kept almost exclusively for its thick soft fur, which was woven mto blankets. The ethnohistoric evidence suggests that the two types of dogs were deliberately maintained as separate populations, with explicit economic reasons for doing so, and thus may constitute true breeds. This pattern of dog use has not been recorded anywhere else in North America. However, the cultural implications of this unique situation cannot be appreciated fully until the issue of whether the wool dog really existed as a separate type during prehistoric times is resolved." taken from the Simon Fraser Univeristy, Archaeology Press website, May 26, 2010.
