My mom has a shih-tzu poodle cross, and he is a horrible little beggar. He learned how to sit up on his hind legs with his front paws curled to his chest, which looked so cute that of course no one could refuse giving him something from the table.
Well, one night, mom and I come into the living room to see Doogie 'sitting pretty' but no one is there to beg from. We found his behaviour quite odd, until we discovered why he was sitting pretty: I had left two Christmas cookies on the table for my mom after I'd gone out to the garage to get the cookies. Doogie could see the cookies on the table, so even though no one was around, he figured if he was sitting pretty, someone would come and share the cookies with him! He eventually did get some of the cookies, as soon as mom and I stopped laughing long enough to sit down and break a piece of cookie to give to him. Smart little dog.
