Hey guys my dog was doing really well with a 7 bumper pile. I started with a mini pile of three in a row, and she did excellent on this too. She would always go for the first bumper and move back in the pile. Today I was extending the distance of the pile away from me and she started picking up the second or third bumper back. Anybody got any tricks to stop this. Should I go back to the mini pile to reinforce picking up the first one. I don't want to come down on her too hard, because I can really see her confidence coming back up, which is excellent! Thanks for the help.
