I've been using Proden Plaque off for my girls for over a month now with good results. I sure notice that plaque isn't building up and their breath smells very fresh all of the time. A lady in Palm Desert when we were on vacation last winter told me about this and that it was recommended by her Hollistic vet. Yes, it's some kind of seaweed formula that you just sprinkle on their food once in the morning. It may seem expensive but for our little babies size you only have to sprinkle a very small pinch on their foods. I'd recommend the product for sure.
