Oral care is about more than making your pets' smiles sparkle-it's an important component of their overall health. In fact, 80% of dogs and 70% of cats begin to show signs of oral disease by age 3. With Advanced Whitening Oral Care Water Additive, dogs and cats can benefit from daily plaque and tartar defense, simply by drinking from their water bowl. Easy to use for both you and your pet-no brushing required!
