Horse pulling is a draft horse competition where horses in harness, usually one or two animals, pull a stone-boat or weighted sled and the winner is the team or animal that can pull the most weight for a short distance.
There are different weight classes and strict rules to avoid animal cruelty. The Belgian horse is the breed most frequently seen, but other draft breeds are also used.
Related sports are tractor pulling and Canine Weight pulling. However, horses pull less weight than tractors, but much more than dogs.
