I never heard of CET chews. I google it and find out that CET chews are tough rawhide chews that have been treated with enzymes to help stop plaque formation, making them more effective than regular chews. I read somewhere that rawhide is not good for Yorkies so Im not sure if this are safe. I will like to hear from someone that have use them. They are rawhide, so i dont I know if I will risk giving in it to Gucci.
