    "Not so great as Angel Eyes"

    Was using Angel Eyes beef flavor worked best; switched when seeing it on the shelf at a better price. Immediately noticed red yeast eye boogies on maltese mix and by two week(s) using max recommended dose it was worse than it has Ever been. Smell(s) like spoiled milk though its a powder. Seems like a-much larger amount of supplement vs the angel eyes amount so do not believe (i am Saving any $$) & obviously poor results. Will not purchase again. If something else IS working don't put yourself through having to get back on top of it by switching too this.

    "Works Good"

    Works pretty good. I would say my malteses eyes are 85-90% better. they are still a lil wet sometimes but nearly as red. I bath her every 2 wks. I still need to clean them abt 1-3 in between bathing. I use a damp cloth and a eyebrow comb. Glad its a more natural approach.

    "Bravo! It works!"

    About to order our 3rd bag of I-Stain. My Pom is free of eye stain. My Malti-poo has far less than she used to have. Very pleased with the product.

    "This product works"

    I used this with all my dogs for the duration of one dog's pregnancy. None of the pups and none of my dogs have any eve stains. The treatment ended 5 months ago and all the eyes are clear.
