Sounds very familar with my Vegas, and yes it was food allergies. For the last year he is on a grain free diet and no more goopy eyes (unless it is seasonal allergies) no licking of the paws and no smell. At 4 months she is going to chew everything, she is teething. Food choice is so hard to figure out! Just when you think you got it, something else changes. Fromm is an excellent food, so it Nature's Variety Instinct, Grain free this is what Vegas is on. He also has an intolerance to chicken so he is strickly on the Salmon flavor. You might want to try a grain free and see if she improves. Vegas did. Also watch her snacks, most are pure crap and also will make them itch. I only give veggies, fruits, yogurt, pumpkin etc....Frozen green beans are probably his favorite.
