I bought a clear eye solution from Petsmart, to remove tearstains and crusted areas under the eyes for dogs. Use a cotton ball to apppy the solution . It works well, however, you have to be very careful because of the delicate area you are working with . the tear stain solution is safe, and gentle. I can't find mine right now at home, however I use it on my yorkie. Your going to also have to keep it up with a regular grooming routine so the build up does not occur.
My yorkie, becomes uncomfortable with tearstains, or crusts under her eyes . it can impede with their eyesight. It is best not to let it build up , then it is a lot easier to treat.
