I would recommend Eye Envy too, I have a black & white cocker that when she was about 7 weeks old had really bad tear staining, I used Eye Envy for 2 weeks, 2 x a day and it's gone completely. We did take her to the vet first though, she said the tear ducts were very small, but would hopefully grow as our pup grew, luckily it has and we no longer have the problem. But I know of lots of people that have used Eye Envy with success, give it a go!
Good luck!
