H O L Y C R A P. I am trying to teach Waffle some more tricks. When I was teaching him "Wafflecopter", he would spin once and I would say "do it again", and he would spin again. Now he spins twice! I said "do it again" when I was teaching him something else at school and he spun around and I made the connection that he thought "do it again" = "spin". I've been saying it over and over too trying to teach him to go backwards. Well I said it today when I was running through his tricks after he did play dead, expecting him to get up and spin around, and he PLAYED DEAD AGAIN. VGDEhjfkgbshdajil then I tried it with some other tricks and he did them all twice in a row. SO SMART. SOOO SMART I CANNOT EVEN BELIEVE HOW SMART THIS DOG IS.
