Our Foster had a nylon Hamilton Collar on when we brought her homefrom the shelter. When we gave her a bath, I noticed that the collar had been rubbing the front of her neck raw.
I went to Target and got a chain collar for about $5.00 and it is working out really well. Her neck can breathe and I can give her guidance through the collar. She seems to like it a lot better.
I got a face wash when I took the old collar off!
