My dog is picky, turns her nose up at every treat, rawhide product, chew toy, food, basically everything in existence. Except one thing: horse trimmings. The ferrier was here this morning, and when I let Lyra out, I realized that she likes them.

However, I'm not sure what the possible problems of this could be. Are there health issues that could come from it? Are they dangerous? Do they break down properly? I just need to know if this is an okay thing to let her eat.
