When I had Annie tear stains were never a problem but this little chi has runny eyes thus staining,I have been using cold tea minus the milk !,I have wiped her eyes twice a dy for 3 days and no more eye watering or staining,granted she has a brown face so the tanning doesn't show so I don't know how the tanning would work on a white face but the tanning does seem to settle minor eye problems,just thought I would let you know ,karen
