For his agility class I had to teach my dog not to be afraid of the tip board. After stepping on it ONCE and having it move (there's a tennis ball beneath it to make it "tippy"...this prepares the dogs for walking the teeter totter) he's was in mortal fear of stepping on the thing. The first time Louie saw it he immediately had to investigate and the fact that it moved didn't bother him one whit! In the first picture you see Ricky skulking away from the thing. In the second picture Louie is looking for a goody. In the third I've placed the goody on the board and Ricky is stretching out to his utmost length to grab the goody before Louie can get it!
