Bests & Worsts Reviews from Amazon

My little dog got very sick with this..I gave hm one and in about an hour I found him with a piece 2" x1" in his mouth. He was carrying it around...he never could have chewed it at this point as he has tiny teeth, and luckily I found it before he choked on it. I was surprised that he had apparently eaten the rest of it so quickly. They seemed pretty hard to me. The next day he had diarrhea EVERYWHERE in his crate and even outside. I was very worried about him . DO NOT BUY. I have since researched it after seeing other negative reviews and they have the reaction in many dogs, and can break into shards causing intestinal damage. Amazon needs to remove these.
