A dog harness is a piece of equipment consisting in part of straps that surround the dog’s torso. It is used to guide, hold, and lift the dog or to utilise its pulling power. It reduces tension on the neck when they pull,[1][2][3] and provides free breathing during daily walks.[4][5] In sports such as mushing and skijoring, where the dog's pulling power is utilized, the harness provides effective use of force while maintaining freedom of movement.[6] These aforementioned kinds of harnesses differ from pet harnesses in that they are specifically designed in order to allow or support a dog in the completion of a working task.
