Since I've had Roxie, a now 1 year old Maltipoo, her reddish-brown tear stains continue and actually are getting worse. No change in diet....she is fed a completely grain free (both wet and dry) diet, I use all stainless steel bowls, filtered water. I have tried Angels Eyes, Angels Eyes Plus, and most recently PetLab's Clear Eyes (expensive). Nothing is working. I asked my groomer to trim the hair off but she said she can't "because it's staining". I have heard about distilled water but also heard that just using distilled water is not good for dogs in the long run, because they need the minerals. I've looked in these forums, but a lot of the posts are older when Angels Eyes had an ingredient that apparently worked, but they have since changed the formula. I would appreciate any advice. Her eyes don't seem "irritated" in any way, she doesn't paw at them but has 1 1/2" long red brown stains in a line down from the inner corner of each eye, and it looks awful. Thanks in advance.
