I listened to Victoria Stillwell and taught Huey to "trade" for whatever he has in his mouth. Unfortunately, this smart bugger now searches the house for stuff he shouldn't have so he can trade for a treat. He's so bad that if you don't realize he has something, he will toss the item in the air and let it clatter on the hardwood, then pick it back up and run out of reach until he's gets his treat in trade...
