I started using this gel when I was looking for good dental prevention products to keep my dogs' teeth as healthy as I could. I admit I tried a lot of gels, pastes, and sprays. As well as water additives. I have found this works best along with using Chlorhexidine Solution as a water additive to my dogs water. I'm very happy with the results of these products used in combination and the way they are keeping my dogs' teeth with little to no plaque build up. The price is good and I use this gel with my Orapup tongue cleaner too. Now my dogs enjoy less trips to the vet for dental care and get great check ups. Well worth the price.
