If your puppy jumps on your friends or strangers when they come to visit you, another
method must be employed. Have the puppy on a leash when a caller comes to the door and as the puppy starts to jump up, pull him back. Ask your friend to reach down and pet him.
Any time you pull your puppy back off balance, say "No, easy," to him. It is best to have a collar on your puppy at this time. The collar should not be heavy and it should fit properly. If you wish to teach your dog later on to stand up against you, try this. Encourage him to stand against you by saying, "Up," and patting your chest. If the dog jumps and leans on you too heavily, gently tap him in the chest. Encourage him to try again, and when he leans against you lightly, praise him with your voice and pet him.
