Query: Do not really notice a difference with this

I bought this to clean the tear stains under my Maltipoo's eyes but I really could not tell a difference. I also purchased the same brand of dry powder that you sprinkle on the dog food and think this works much better than this product. I would not buy it again since it doesn't do any better than his regular dog shampoo.
