Product Description: Just a sprinkle a day keeps the tear stains away! As you keep trimming the stained areas, the newly grown coat will be totally clear. The growth pattern will determine if it will be completely tear stain free anywhere from 3-5 weeks. Contains beef liver and tylosin as tartrate.
It took a while for us to see the difference, but we noticed IMMEDIATELY when we stopped using this product. It really stopped the staining on our Shih Tzu. It was recommended to me by a Maltese owner and again by a friend who shows dogs. I have yet to find anything that is easier (just sprinkle on their food!) and works better!!!
