FRESH BREATH dog treats are natural, ethical, low-calorie, hand-baked mini-bones that dogs love. They include chicken, parsley, peppermint oil and chicory. Parsley is a source of chlorophyll, a natural deodoriser. Peppermint not only gives breath a fresh scent, it can also aid digestion. Poor digestion is often a cause of bad breath. Chicory is a natural prebiotic that can help the proper functioning of the digestive system. The biscuit’s abrasive action can clean your dog’s teeth as they chew.
