Hi Kevin, I have one of each colour. My male Bulldozer is brown with a little bit of white on his neck and front paws, but his eyes are brown, and he doesn't have any tear stains, but my female Blosssom is all white with a few brown spots on her back, and she is the one with the allergies to chicken, salmon, corn and grains. She also seems to have more skin issues than her brother. They are siblings and litter mates, so have the same parents, but she is much more sensitive than he is. She does have tear stains, they're not really bad, but they're there and noticeable. I wipe them with a damp cloth, but they don't totally go away. We feed our guys Fromms Beef Fritatta, as beef is the only protein she seems to tolerate without major allergy symptoms, and good poops, with no diarrhea. She isn't totally symptom free though, as she still sometimes will get a pink face, and will sometimes lick her paws, but not often. I don't know what or if it's the food or some ingredient in the food that she is sensitive to, but it's the only food that we've tried that she does well on. I hope she doesn't develop an allergy to this brand as well. I'll definetely be watching this thread to see what advice you get, as I'm interested in it as well. I'm sure other members with more experience will be along soon to help.
