I have two Maltese. They are both 2 years old. I have tried just about everything on the market for the eye staining problem, topically and orally. My dogs are extremely healthy, eat only the best natural food, and are groomed regularly, so I know diet, etc. is not the issue.

Angel eyes is the only thing that has kept them stain free.

It is expensive, and frankly, I wish I could buy it cheaper, especially since it looks like it is going to be a daily thing for their lives.

Great product...give it a try!
