Because your dog's bad breath could be a sign of serious dental problems, the experts at Purina developed Purina® Dentalife® ActivFresh®, containing natural spirulina and honey, to help fight bad breath at its source rather than just covering it up.

ActivFresh® is designed with the Dentalife® shape, size, and chewy, porous texture that is scientifically proven to reduce tartar build-up. Don't hide bad breath, fight it at it's source with ActivFresh®.
