through special breeding, spitz types have evolved to help humans in three ways: hunting, herding, and pulling sleds. smaller breeds such as the finnish spitz and the lundehund were used in scandinavia to hunt birds and smaller mammals. larger breeds such as the karelian bear dog and the norwegian elkhound were used for hunting large animals like moose and elk. the largest of all the spitz types, notably the canadian eskimo dog and the greenland dog, were used to pull sleds up until the 19th century.
