We have had two collies and they were wonderful dogs but decided to go to the Sheltie also and it was not a good experience. I think the dog was mental. He did some really strange things and didn't like anyone, he was a loner. They are great dogs but we got a stinker. I have a friend who has one that is 16 and he is a real sweetie.Yours look beautiful, enjoy him. We lost our Old English right before Christmas and we miss her so much.
