Drafting dog

[2] These dogs are working animals, traditionally used for pulling small carts called dogcarts.

[4] In the 20th century, headcollars were introduced to make control simpler, and they have become standard equipment in a variety of designs.

[5] Several popular breeds were once bred specifically to pull carts, including Collies, Bernese Mountain Dogs, St. Bernards, Bouvier des Flandres, Newfoundlands and Rottweilers, though they often found other uses such as guard dogs and sheepdogs.

[10] The Dutch-Belgian artist Henriëtte Ronner-Knip (1821–1909) painted many pictures in the Romantic style of drafting dogs pulling dogcarts.

[11] Sled dogs were used to pull equipment and men efficiently over the snow and ice on Roald Amundsen's 1911 expedition to the South Pole.
