Dogs may nip at visitors for a few common reasons, including excitement, distress, or fear. Puppies might nip out of excitement when they want to play or explore. They can also nip if they’re feeling distressed, which might happen if they’re anxious, frustrated, bored, or in pain. Sometimes, dogs nip because they’re afraid of strangers or crowds, or if they’re trying to assert dominance. To help manage this behavior, pay attention to your dog’s body language and understand dog consent. A dog that is loose and wiggly is probably feeling playful, while a stiff and cautious dog might be anxious or scared. We suggest that when a new person meets your dog, they should reach out their hand, stop about 2-3 inches from your dog’s nose, and then wait for the puppy or adult dog to lean forward and see if they nudge or lick the hand. Try associating guests with positive things, like treats or playtime, to create a positive experience. Avoid using physical punishment, as it can make your dog more fearful. Instead, focus on consistent and gentle training to help your dog feel more secure. To stop a dog from nipping at people, you need to help the dog see that visitors are a positive experience. The key is to use positive training methods. This helps the dog connect new people with fun and rewards. When the dog learns that meeting new people can lead to good things, they will be less likely to nip. Exercising your dog before practicing this strategy to stop dog nipping will help set him up for success. It might also help to put your dog away again before guests leave to avoid overwhelming them.
