The Sure-Fit Harness features 5 points of adjustability to fit most any dog. When your dog tries to run ahead during your walk, the harness places pressure on the breastbone instead of the throat. This makes it easier and safer to control your dog and also prevents choking and gagging. It’s also a great option for very small dogs with delicate throats. The Sure-Fit Harness features an easy-on, easy-off design with 2 quick-snap buckles. For dogs who slip out of traditional collars or who pull on the leash, the Sure-Fit Harness will keep them under control.
