Query: tastes great but does not reduce tartar

I'm giving this product one star simply because it does not do what it advertises, that is reduce tartar.First off my dog loved the taste, but why wouldn't he when the first four ingredients are different cheeses. After about a month there was no noticeable difference in my dog's breath or tartar.One thing you also want to consider is that the recommended dose is 1 teaspoon/15 lbs your dog weighs. My dog weighs in at 45 lbs so that is three teaspoons/day.So if you want to feed your dog a powder treat with meals then go for it. If you're looking for something to reduce tartar then keep looking because this won't do it.
