My Papillion (small lap dog) is smart. He likes to steal 'people food' off the table by jumping on a chair then onto the table. So I rolled (the chairs are on casters) all the chairs far away from the table. While in the kitchen I thought I heard something and when I looked my little dog had rolled a chair back to the table, used it to get on the table and was happily finishing a hamburger. His little tummy was bulging, I was still hungry. Guess Im trained.
