I just got a beautiful English Setter pup. She is going to be a tricolor but right now she is only 7 weeks old and is mostly white with some of the black ticking showing up. She has a really bad case of stained eye. The fur under the corner of her eyes is stained a dark reddish brown color. The vet told me it was caused by an enzyme in her tears. My question is will this go away as she gets older? Also is there any treatment I can do that won't harm the puppies eyes?

Thanks,
Chuck
