This product helps to support teeth and gum health in canines. It is intended to aid in keeping plaque, tartar, and bad breath at bay when one is too busy to brush a dog's teeth. Key ingredients include zeolites which help to keep plaque from sticking to teeth and propolis which is an anti-fungal, anti-bacterial, and helps reduce bad breath. This is an enticing liver flavor dogs love and is intended to be ingested. This is not intended to replace regular dental care with a veterinarian.
