10. Allowing leash pulling

Some dogs seem so focused on reaching their destination that they entirely disregard the person holding the leash. This behavior is not only hazardous but also frustrating. However, it is not an inevitable problem. “When your dog pulls on the leash, it indicates she’s focused on something other than you,” explains Fred Zorn, a New Jersey-based dog trainer and creator of the kids’ video dog-training series Pipe Cleaner Pups. “Your objective is to teach the dog to want to stay with you. This transforms the leash from a tool of control into a means of communication.”

If conventional methods aren’t effective, consider using a headcollar like the Gentle Leader. Additionally, avoid making other common puppy training mistakes that you might regret later.
