The same rules for when you meet a new dog apply for when a new person meets your dog. Make sure visitors know the house rules in advance so you can easily manage your dog’s behavior during the introduction. Do not allow the dog to bark or jump up on the visitor. Visitors should avoid greeting the dog verbally and should not make eye contact, instead waiting for the dog to get comfortable with their scent and approaching with a gentle touch or nuzzle. At that point, your guest may be affectionate with your dog – if your guest wishes to.
Keep in mind that your dog can remember many, many distinct smells, so they will form a lasting impression of a guest after just a few meetings. It’s worth taking the time to make sure the introduction goes smoothly.
