Because your dog lives with humans, he is going to have to learn to deal with frustration sometimes, because you should not let things always go his way if you are to be a responsible dog owner.
When your puppy eventually becomes separated from his littermates, he will most likely carry on his playful behavior with you and your family members. This is often the cause for most puppies trying to bite our hands, or clothing. This behavior usually happens when your puppy is excited and wants to play, rather than a sign of aggression.
By playing games with your dog, you can reduce boredom, give him chance to display his natural jumping behavior, and reduce any destructive activity he might be doing in your home.
