Rawhide bone ruining appetite?

I agree raw hides are dangerous. I would only give them to small pups teething and small dogs SUPERVISED! Larger dogs have no trouble chewing pieces off & swallowing them. Free fed dogs often times become picky eaters. So it may have nothing to do with the rawhide. But if the dog acts out of the ordinary I would have a vet check it. Swollen abdomen, retching. Lethargic.
