Carting

[1] 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.

Many working breeds are happier when given a job or task, and carting/sulky driving can be a rewarding hobby for both dog and owner.

A widely used model is the dorsal hitch, which involves only one shaft from the sulky that has negative weight on the dog's harness.

The dorsal hitch also allows easier going for the dog, with free range of movement as opposed to confining shafts on either side.

The general rule is that the total load (sulky and driver) should not exceed three times the weight of the dog doing the pulling.
