Leonard also had trouble with "down". He wouldn't do it no matter what and on the day of the final test I took some chopped up hot dogs with me to bribe him. We went through the obstacle course and on the "down stations" I had him sit and then gave the "down" hand signal cupping the hot dog. He went down so fast! I was shouting OMG he went down so loud that I think everyone in the store heard and they all congratulated us afterwards. Something clicked and he still goes "down" to get his treats for being a good boy outside.
