Thanks PacRakMG. I will talk to the vet next time she does her rounds.
No, you diddnt read anything wrong, I do have to watch him all the time with new kids and dogs which is EXACTLY why I am so worried about him. I agree that you can never know 100% how they will react which is what I really worry about. Mostly because I know what he is like now, but there was 5 whole years of expereiences before I got him and I have no idea when or if his past might come back to bite someone!
