I have a 7 month old Border Collie, who is as smart as they told me she would be. However, I was not very happy with the dog trainer we had so switched to another one who has a really good reputation. However, after two lessons, my dog has now gone "strange". Before,she was keen to obey and please and quick to learn. Now she will not obey, sits and stares at me when I call her to come and generally seems to have gone backwards. The new trainer says this is a "phase" and that the dog:confused: is putting short term memory into long term memory, and I should make a game of it. I want to believe her, but would hate for my pup to be ruined! Can anyone help? Have I confused her by taking her to another trainer?
