Ok well we had session 4 a couple of days ago but I quit pretty quickily as all Ollie wanted to do was throw the rings everywhere, even when the bowl was right in front of him he was determined to throw it to either side.
Session 5 happened that evening, thankfully with more success, he did so well at one stage I really thought he had got it so I ended the session in order to leave it on a positive note.
Session 6 happened yesterday. He started off with the first few commands really well, after that he seemed to be getting more enjoyment from watching them hit the floor. I do actually think he is aware of how its supposed to be done, if he misses the bowl he tries to pull the bowl out my hands, he also seems to look very carefully to see where it landed. Session 6 should have been high motivation as it was about an hour before feeding.
