Shake Hands

Start by having your dog sit. Say, "Shake hands," and take his paw with your hand. Hold his paw and say, "Good dog!" Let go of his paw. Do this a few times every day.
TIP:
After a while, say, "Shake hands," but don't take his paw. See if he raises his paw by himself. If not, keep showing him what to do by saying, "Shake hands," and taking his paw with your hand. Your dog is not slow; he is just learning!
