What all do you guys do for the tear stains from your dogs eyes? I have a white Maltese dog and he has always had SOME trouble, nothing too awful bad. He is on a grain-free diet, drinks RO water only and we try to keep him away from the human food. I found that the grain-free diet keeps his ear infections under control as does his skin irritations. But he sure is a licker! He licks his paws and chest a lot.
