Bests & Worsts Reviews from Amazon

My dogs are very healthy and have never had digestive issues. I gave both dogs a Greenie the day the treats arrived, and both of them had black, tarry diarrhea within four hours. For about 24 hours, we were all miserable. I normally feed my pups rawhide treats and Bully sticks, and they've never had a problem with any treat before. I seldom give a bad review, but these treats deserve one.
