Anyone familiar with this product or ever used it before? Several people were talking about how well it worked on another forum I go to and it got me curious. Even though Kirby's teeth are currently good, I'm always on the look out for anything that promotes healthy tarter free teeth since Papillons are known to have teeth problems. I already brush his teeth with PetzLife gel but what got me interested in this one is it is suppose to be purely systematic and you just add a touch to their food each day with no need to brush.
