Dogs jump up on people for one reason: to get attention. Teach your puppy or dog to “sit” for attention or praise of any kind. When he jumps on you, use a lowered tone of voice and lean towards the dog, saying “off.” He will have no choice but to back away from you. When he does, tell him to “sit” so that he firmly plants his bottom on the ground. Offer him calm praise for obeying you. Soon all you will have to say to your dog is “sit,” and he will comply readily because he knows he will be rewarded.
