Anything I can do to reduce weepy eyes?

My 4 month old papillon pup has weepy eyes, that (to my suprise) seemed to get worse when I switched him from Science Diet to Wellness Just for Puppy. His vet said it's just tear stains and not an infection, and it's common in small dogs. Is there anything I can do to reduce it - a diffrent food or anything?

This is called tear staining. Here is some info and grooming tips: http://www.lowchensaustralia.com/grooming/grooming4.htmWellness is a much better brand than Science Diet is.

I have no idea, I just got a chihuahua/ mini pinscher mix and she has the same problem. It may be allergies. I went to petco and got these wipes called "petwipes on the go" by petkin. they are bathing wipes I keep those in my purse so if I notice her eyes are weeping I take one of those out and wipe her eyes. They come in a pack of like 20, are individualy wrapped and are like 20 dollars. Hope that helps
