I haven't had one that has gone backwards. Once they earn the right out of the crate they have free roam of house. I have 5 dogs and only one in a crate. I put the garbage can away because the oldest has always had an issue with that, so I just remove it and that takes care of that. Robyn does grab my shoe and sleeps with it, she doesn't eat it, but she keeps it right by her. The cats also have free roam. Every now and then I come home to them curled up together. They don't have accidents or eat anything while I'm gone, if they did I probably wouldn't know who it was anyway.
