I have been using angel eyes for years. For the last 6 months it appears that the product is no longer working on my dog. I'm not sure if there was a formula change but I will not be purchasing another bottle.
I have also been using the eye wipes and they are not making much of a difference on the tear stains. I am saddened by this as I was a fan of the Angel Eyes product and would tell all of my friends how great it worked.
