This is how a lot of alleged "professional" trainers accomplish their money! - It's important that you DO NOT punish or harshly correct your dog for this behavior. It is not something that he can easily control, and he's certainly not doing it on purpose. Punishing a dog for this behavior can cause emotional distress and lead to more problems for you and the dog in the long run. When you catch him in the act, you can interrupt him (a firm "No!" followed by praise when he stops should suffice) but don't punish him. Keep your cool, and try to be sympathetic: he doesn't mean to do it, after all!
