Carting

Carting is a dog sport or activity in which a dog (usually a large breed) pulls a dogcart filled with supplies, such as farm goods, camping equipment, groceries or firewood, but sometimes pulling people. Carting as a sport is also known as dryland mushing and is practiced all around the world, often to keep winter sled dogs in competition form during the off-season. (Note that the term "dogcart" is primarily used to mean a particular type of light horse-drawn vehicle.)
