I've found that grains cause stains more than anything for my Crested. Other things can cause them, however. It's possible your dog is sensitive to something in the NB, or it's highly possible that she is reacting to an environmental problem (airborne allergens, chemicals, carpets).
To get a better idea of whether it's the food, try her on a very simple diet - get a sample of something if you can - you'll be able to tell right away (at least, I've noticed that tear stains appear within hours of being exposed to something problematic for Zhi).
Cal Natural is always glad to send samples - NB has another formula that I think is a little simpler than their duck (fish and something). And I think Pinnacle has a fish formula without grains, also.
Good luck!
