You don't "teach" a dog or puppy to show love, you are blessed with what they feel is appropriate affection! Most puppies I've been around DON'T at all like to be held or cuddled, so if you're trying to teach them to like something they don't, good luck with that LOL! Just wait, let him or her grow up a little, and they'll be much more receptive!
