Training is going really well and we are making great progress with stop whistle, steadiness and working with other dogs, etc. What we're having a problem with at the moment are memory retrieves. Memory retrieves were going really well, but, over the last few weeks Maisie is struggling to stay at heel while we walk away from the dummy, ball, etc, and turns back to retrieve it. She is literally licking her lips at the thought of getting the retrieve At training she can be stopped by the trainer, but on my own this is impossible! We were at the point of sending two dummies out, sending her for the first one and then the second, now she just tries to get to the second one straight away unless I walk out to the first one and back again. This seems to reset her excitement levels. I've gone back to basics....drop the retrieve, let her see it, walk on at heel on lead and then turn, sit and send back. Even on lead she is looking back and I can feel her determination to get the retrieve. Any tips, or do I just keep going with the basics?
