Sam's Yams are made from orange fleshed, sweet potato (though sometimes you may find them labeled as "yams" at the grocery store.) These chews are highly nutritious and excellent for your dog’s teeth and health. Sweet potato is very high in anti-oxidants. Nothing artificial, no sweeteners, colors, or processed food items. Sam’s Yams are made only of human food quality, fresh sweet potato and nothing more. The trick is in the drying process, where the sweet potato is transformed into a chew that has characteristics similar to rawhide or jerky. Basically, a vegetable rawhide-like chew. Best of all, dogs love them! Smaller breeds will chew these for fifteen to twenty five minutes. Medium to larger sized dogs will chew them faster, of course. Will not stain carpets.
