How do u train a puppy?

Well, they're gonna want a reward....a nice belly scratch! Whenever they jump, hit him on the nose lightly and say "no!". To sit...hmm...scratch it's head and then it should sit? Say "sit!" Whenever he sits, and when he doesn't, get him in the position and say "sit." Easy! And you might want to teach him "Stay!" too. Good luck!I luv pups!
