The Crosscheck Harness is a training harness that reduces a dog’s pulling via a girth checking system. It functions similarly to a martingale but instead performs a checking function around the dog’s girth rather than its neck. This alternative limited-slip checking system allows the handler to give a correctional tug as the dog begins to pull, teaching the dog to walk beside them in an effective and humane way while doubling as a solution for escape artists. The side checking feature is most effective when the dog is on the left side of the handler.
