"I bought this for my dog after his breath was really starting to get to me and he loves it. The day after we started using it, the dreaded "doggy breath" was gone, and the more we've used it, the healthier he seems to be. His gums and teeth look great, his bad breath is gone, and his tongue looks really pink. Plus, now he won't drink if we don't add it to his water. After I rinse his bowl and refill it, he'll just sit there and stare at it until I add some. Its great =]"
