BarkStix Fart Busters Fart Free Dog Treats 4 oz. - these all meat dog treats are made in the USA. Made from pure whole free-range chicken with a proprietary blend (human grade) of digestive enzymes that can aid digestion. Better digestion means less gas, helps with those aromatic moments. * DEE’S REVIEW: This treat really works! I have a 95-pound dog that used to be able to clear everyone out of the room; he now gets six of these small treats per day and no more gas problem.
