My dog became very ill last summer and couldn't eat anything and was very listless. Not like her at all. I took her to the vet and she X-rayed her and her stomach and intestinal area were very inflamed. She asked me if I had been giving her any kind of "treats." I told her I had. Some of that was the above "treat." She told me to throw it away and NEVER give her any more treats except for the all natural, easy to digest ones. However, I now give her none at all. After $350 for X-Rays, blood tests, and treatment, she has been fine. All these things are very hard for them to digest and secondly, there can be all kinds of bacteria or harmful chemicals in these things. Best to be safe than sorry.
