Angels' Eyes Worked
Our Maltese had a face which was covered with ugly, reddish stains. We tried eliminating foods with red dye, giving her bottled water and topical solutions--nothing worked.
I found a website which talked about Angels' Eyes and the success many dog owners had with it. I figured it couldn't hurt to try it, and it worked like a miracle.
There was significant improvement in our dog's face in about two weeks. The entire problem cleared up in a month.
