I have a 6 month old female lab who about 2 months ago started with dry eye
left side. She also has excess drool coming from her left side of her mouth same time dry
eye started. Thought maybe drool was from teething but it's not. Have seen 2 different Ophthalmologists, have had the fluorescein stain test, schirmer several times (left eye zero, now 5, right eye dropping from 17 to 8, no clue why), on meds (neopolybac, tacrolimus, cyclosporine, artificial tear ointment, genteal, pilocarpine).
