Apple cider vinegar didn't help my dog. However, I found that keeping his eyes clear of discharge by using a clean index or thumb finger pad as often as possible cured the issue. You must be very gentle! At first your dog may not particularly like this being done. However, if you are very gentle with the process, your dog will soon allow you to clear his/her eyes and will be forever grateful for this ritual.
