Buckley has a bald spot on his neck (front) where his collar is. He always scratches his neck and I noticed the bald spot so I took his collar off to look better and it's a nice size spot so I left it off to see what would happen. Could he be allergic to his collar? He hasn't scratched since I took it off. He doesn't act like it bothers him. I put his harness on him when he goes outside
