Ok so I have taken Sasha to Petsmart for boarding and she was never allowed in group play because they kicked her out. I have also gone through Petsmart 1 on 1 training and am just not pleased! So I took her to another location by my house that unlike Petsmart has an acre of land that they can go out an play in instead of having group play in doors. I took her to see how she would do for one day. I was told she did great for about an hour, she was having fun playing with the other dogs etc... But then they let the little dogs into the yard and she would not leave them alone chasing them and pinning them down. She got kicked out of that group play also. The trainer there said she has a high prey drive but only for little dogs. He recommends me to do some training with him, and to also try the clicker training. Not sure if anyone else has ran into this issue or not and how the corrected it. I feel bad for boarding her and her not being able to do group play time. Also when I walk her I do notice she goes crazy when we pass a smaller dog. Its very embarrassing. I have tried everything the petsmart trainer showed me but at $89 every 30 minute session I couldn't keep justifying the price when I saw no progress being made.
