I really like the C.E.T. by Virbac enzymatic pet toothpaste. We use the Vanilla Mint flavor and just also bought the poultry flavor one. I think the toothpaste works well and the dogs like it. Most vet offices sell it, but you can also find it on amazon.com (also, if you shop at amazon, you can visit the
yorkie haven rescue website and click the amazon link to shop and have a portion of the sale go to help the foster pups!)
