Our eight-year-old Jack Russell Terrier had very bad breath and ugly black-stain teeth for most of her life. We tried everything, chopping parsley and adding it to her food, brushing her teeth with pet toothpaste, Greenies which gave her hemorrhoids, tried getting the Vet to clean her teeth but he never did, and everything we tried, failed. That is until I tried a drop of hydrogen peroxide. Now I've gradually worked up to adding an eye-dropper full (5-8 drops) to her water bowls daily, and her breath and teeth have improved much to our amazement. Her black teeth are now pure white, her breath is fresh and she seems to have a lot of new energy. Now I'm ready to give it a try myself for my arthritis.
