The SideWalker® creates a more enjoyable walking experience for you and your dog. Gently corrects overly enthusiastic leash pulling and helps your dog learn appropriate on-leash behavior. The ‘self-teaching’ design assists in reinforcing appropriate leash training and eliminating excessive pulling. The SideWalker has 5 adjustable settings from low to high plus a vibration option so you can select a setting appropriate for your dog. When the dog pulls on the leash, the pressure of the collar strap on the SideWalker activates either a vibration or a stimulation. The vibration or stimulation gradually increases as the dog pulls and resets when the pulling stops.
