My 4 1/2 month (white) pup Winston has brownish/red tear staining on just the left eye. I've tied tear staining wipes and other topical solutions from pet stores, but nothing seems to really help. I wipe his face frequently with baby wipes also. Was wondering if this could be related to teething and if anyone has found anything that works for removing the stains. I have heard about angel eyes, but I'm hesitant to start him on that since he is so young. He has a clean bill of health from the vets office, she seemed to think it was nothing to worry about and suggested using no tears shampoo. I did try that but the stain is stubborn and still there. Would like to know if anyone has had any success with removing tear staining on their white dogs? Thanks in advance for your help.
