READ ENTIRE REVIEW! In Sept. of 2008 I wrote, "I can't really write much of a review on whether the product works or not. It smells so bad I have to disguise it in something to get the dog to eat it. Usually try to get the powder into some cheese or meat in order for her to swallow it. Sprinkling it on the food is just a waste of food because she won't get near it. Maybe someone has a good tip on how to get it into the dog!" Today, May 27, 2009, I have found that it still "smells bad," but if I put 1/4 tsp or less twice a day it really works to keep eye stain away and she doesn't seem to mind the taste!!! SO, NOW, I GIVE IT A THUMBS UP!!!
