| It's to keep the dog from pulling on the leash. When the dog pulls, the leash tightens around it's waist making it uncomfortable for the dog to continue to pull.
The only reason I know this is because the "instructor" at the petco puppy class I took Red to told us this and showed one couple how to use it on their lab/sharpei mix who was a bad puller. It did seem to keep him from pulling too much, but it was avoiding the problem, imo, and I wouldn't do it on my own dog. |
