Thanks from an unexpected quarter.I have an aging cockapoo - at least that's what we think he is; he's a stray rescue, so no one really knows. Anyway, he has the stereo-typical cocker ears (constantly infecting) and poodle eyes (constantly weeping,) so we're fighting issues with him pretty much year-round ... poor Old Man. I'll add these to my medicine kit.Here you go:

I recommend the VitA-Pos eye ointment for the night.
