Query: Garbage...

I bought this because my English Bulldog was getting tear stains on her face and paws. After getting the package, I immediately gave her a bath with the shampoo and saw absolutely no difference. I thought that maybe it would work gradually over a little bit of time. Well, It's been a month and I see no results, not even a little. Garbage, IMO.
