Providing a great source of the superfood Spirulina, these unique, star-shaped sticks encourage the body's natural mouth and teeth cleaning process throughout chewing and long after ingestion. If you notice a change in your dog, such as reluctance to eat, favoring one side of the mouth, lack of grooming, or staining around the mouth, it may be the onset of dental disease and he should be seen by a vet. The treats are low in fat with no artificial flavorings or colorants.
