I get Ollie's food (Acana) at a store that is all about healthy animals. I mentioned using Angel Eyes for his eye stains that started up a couple months ago. She ask me if I had probiotics for the stain rather than the low antiobiotic in Angel Eyes. She gave me some organic to sprinkle on his food once a day for a few weeks. Have any of you heard of this? I wash his eyes a couple times a day and have no idea why the stain started. He was doing so well.
