Using TropiClean Fresh Breath Dental Health Solution is super easy. Just add it to your dog's water bowl according to the instructions on the package. You don't need to brush your dog's teeth separately, as the additive will do the work while your dog drinks water. Remember, the product is going through a packaging change, so you might get the new or old version. It's tasteless, so your dog won't notice it in their water. For best results, use it daily as directed. In about 14 days, you should start to see a difference in your dog's breath. But keep in mind, results can vary. Establishing this daily oral care routine helps protect your dog from periodontal disease, which can be harmful to their internal organs. There's no special maintenance needed for the product itself. Just store it in a cool, dry place. Available in 473 mL and 1 L sizes, choose the one that suits your needs.
