How to Stop a Dog From Lunging. Walking your dog is great exercise and bonding for the both of you. But when you have a dog that lunges out at people or animals as you pass, it could quickly turn into an event that you dread and that is potentially dangerous. Follow these steps to learn to stop your dog from jumping out while on the leash.
Understand why your dog is jumping when on the leash so you know when to expect it. Your dog may do this when he sees another dog, person, animal or all of these, so bring your dog closer to you when you see any of these.
Resist the urge to pull the opposite direction when your dog beings to lunge forward. This can cause more jumping and pulling to where the dog may think it is a game, and they do instinctively resist pressure.
Keep your dog at your side while walking so that she cannot get ahead of you to jump out at someone or something. Use a halter or leader around your dog's mouth, a body harness, or a shorter leash that does not expand out as your dog moves away from you.
Walk with confidence when you're out with your dog. When you're calm and assertive, looking ahead and not worrying about your dog constantly as you walk you decrease your chances of jumping out.
Reward good behavior by taking treats along when you walk. When your dog resists the urge to jump, praise him and give him a treat. When he does lunge give a command in a firm calm voice; even a simple "no" will work.
