Sparkle Dental toys are the perfect product to clean your dog teeth without having to actually do it. You just have to let your dog play with the toy and let the soft plastic bristle and brushes do their job. The toy has two types of brushes| some toothbrush like bristle that clean areas that are difficult to access, and the soft plastic brushes that remove tartar. You can put toothpaste a few times a week to increase the cleaning effect of the brushes.
