Sam"s Yams Yam Bones are natural-cut 100% sweet potato dog treats with the skin on and the same thickness as our Big Boyz. We shape them into bones by hand and then infuse in chamomile tea. They look and smell fantastic. They"re tastefully presented in a white paper craft bag with a cellophane bag inside. Sam"s Yams are totally digestible and an excellent nutritional chew, far superior to many other healthy dog treats in any nutritional comparison. Sam"s Yams products contain no wheat gluten—a substance most dogs (50%) are allergic to—or other additives. Veterinarians recommend our product because it is hypo-allergenic.
