I switched food to grain free and also filtered water at the same time and that made June's stains go away. Not sure which helped, or if it was the combination..
I can't seem to rid poor Sebastian of the tear stains either , still trying everything but I am thinking allergies . Yesterday he woke up all pink in the face so I gave him Benadryl and he looked better but the the tear stains never seem to get better almost sometimes then they are bad again
I've been using Bert's Bees for Dogs Tear Stain Remover with complete success. No more tear stains! It took a few weeks, but the tear stains vanished. I drip both sides of a cotton round wipe, then use a side on each tear stain. I gently wipe up, down and back and forth. Daisy likes it just fine. I do it once a day.
