I have tried and and would not recommend. Have to agree with other comments about having dogs on antibiotics, even is it is only a very small amount. I have tried quite a few if not most products sold and now do it my own way that works for me.
It's important to keep the eye area dry. My dogs who need it have the stained hair cleaned by spraying a no rinse shampoo on to a face cloth and wiping / rubbing hair till cloth comes aways clean. I then wipe with damp cotton wool to remove any shampoo that may remain then dry throughly with another clean face cloth. This is done daily with all dogs, and 2 or 3 times a day for anyone with excess staining.
One dog I had was so bad in one eye we went to the vet and it was found he had no tear duct, they operated and created one and that totally changed his appearance. Was so nice to see him with a white face again,
ps My dogs eyes are a lot better since I removed the auto scent / plug in air freshners.
