I'm going to try this remedy too. Blossom has started getting some staining around her eyes. My guys get Fromms Beef twice a day, and ACV in their drinking water. Her eyes water sometimes since her cherry eye surgeries, so I wonder if this is some of the cause of the staining? Bulldozer doesn't have any eye staining and he didn't have cherry eye problems, also he's mostly brown in colour, and Blossom is mostly white, and I think dogs that have white fur have more tear eye problems.
