I just got my two a new chewing treat. It's dried fish skins from Iceland. They are natural and I think they're good for them. They both love them so much. They get them at night when my boyfriend and I like to watch a movie. Wesley knows where I keep them and cries for them all day, he loves them so much.
They're website is:

You might want to check them out. I'd also love to know what you think about them, if you try them.
