Providing a great source of the superfood Spirulina, these unique star-shaped sticks encourage the natural cleaning process of the mouth and teeth throughout the bite and long after ingestion. If you notice a change in your dog's behavior, such as not wanting to eat, favoring one side of the mouth, decreased need for self-cleaning, or discoloration around the mouth, this may be a sign of the onset of dental disease, and you should be seen by your veterinarian. The candy is low in fat and contains no artificial flavors or colourings.
