Review on DreamBone Spirals Variety Pack, No-Rawhide Chews For Dogs, 32 Spiral Chews by Eddie Pollard

I buy these from time to time for some different flavors for my elderly dog. The one thing I worry about is what these chews are actually made of? They get really hard if left out --almost like hard plastic and I pick them up from the floor so that my dog doesn't end up eating them that way. He does like the flavor wraps that are twisted around the chews. That's what he eats. Not sure I would recommend giving these whole spirals due to this unknown hard matter. Personally, I don't think it's that healthy.
