remedy for excess dog tearing stains : My dog had horrible tear stains. I tried cleaning his face everyday; it would not come out.So I just gave up on washing his face. I started adding apple cider vinegar, extra virgin coconut oil, and crushed raw garlic to each of his meals. I originally did this so he could lose weight, and help prevent fleas. He is losing weight slowly. Plus the tear stains that were stuck on his entire face are 90% gone. buddy loves the way it makes his food taste. I just small amounts of the three remedies and mix well in his food.
