I have 5 poodles all with the tear staining problem. One looked as if I'd put blood all over her face. (Am getting a Yorkie on Saturday.) After trying several home cures I heard about Angels' Eyes. You can find it on the Internet (or e-mail me
jimbrasel@gmail.com). I can't say enough favorable things about Angles' Eyes. Within 10 days I could see an improvement in all the dogs. At that point I could remove what stains there were with tap water and a cotton ball. At this time there are no stains. You are suppose to use Angels' Eye for 9 months, decreasing the dosage over the time. My dogs have clean faces. I will go the full 9 months
