greeting visitors can often be an adventure that is full of energy and emotion for both you and your dog. One way of making the situation less charged is to teach your dog a “place” cue. Begin by developing a good, solid, sit or down stay.

often times nipping can be the sign of a more serious problem than just an impulse control issue. If the nipping problem doesn’t cease, you should seek the consult of a certified dog professional. Biting, regardless how minor it may seem can lead to more serious situations.

Don’t let your dog continue this behavior. Nikole’s suggestion of establishing a solid sit-stay is a good one. In between times, keep the dog on a leash when visitors come and keep him away from the people. Make him lie down beside you. Nipping will lead to bigger things if not “nipped in the bud.”

Teaching bite inhibition is the most important part of your puppy’s entire education. Certainly puppy biting behavior must eventually be eliminated. There are two-step processes: first, to inhibit the force of puppy bites, and, second, to lessen the frequency of puppy bites. Check this link for more detailed explanation.
