Gentle Leader Headcollar Black If your dog lunges and jumps when he sees squirrels (or sniffs other dogs), the Gentle Leader Headcollar is a great way to teach him better leash manners. Use this tool to train your most determined puller while still allowing him full range of motion to bark, eat, drink, and play fetch. Unlike other harnesses, the Gentle Leader Headcollar loops around your dog's nose rather than his neck or shoulders. When your dog pulls, the headcollar gently moves his head towards you, allowing him to refocus his attention on you and away from the enticing squirrels and distracting smells. The best part is that once your dog has mastered proper walk manners, you will most likely only need to use the headcollar as a backup during situations requiring a little more control, such as vet visits or dog park play dates.
