I was looking at some of the links you posted, I was just going to mention to try to get a wider type of collar, some of those pics were too thin. With her chain being attached the thin ones could break easily and also damage her neck if she pulled hard if she saw something cool and ran to the end of her chain. The wider ones distribute the pull exerted on her neck so it wouldn't hurt her accidentally. I think the pic of the nylon one that was posted looked pretty good that way.
