mickey just recently learned lie down. even after wave lol, lie down is boring

we taught him by getting him in a sit position. then i would say "lie down" and take his arms and gently pull them down until he was lying. then i said "lie down" and gave him a treat. after a few practices he knew it right away. this might not be the right way but it got done here's infor from purinapuppychow.com

--Start with your puppy in the sit position. Then, using a treat or piece of food, lead your dog's nose down and out while giving the "down" command. Don't worry. With food in your hand, your puppy is sure to follow.

Repeat often. This command can come in very handy when your puppy is headed into a dangerous situation. --

good luck
