Does your dog growl, bark, lunge and pull in the direction of other dogs? Is your dog wild and crazy on a leash? If your dog does, it's your job to correct that behavior. Get help from a dog trainer. Also it's polite to say I'm sorry if your dog disturbs other people and their dogs on their walk. You should be embarrassed by their behavior. Most people want to walk their dog in peace. They don't want to be in the middle of a dog fight or break one up. Besides almost no one knows how to do that. If you are someone who is struggling with your dogs reactivity nothing can change it other than training. No new leash or harness is going to solve it. You have to take steps to correct it through behavior modification, redirection and consistency. This course is for you!
