Ack, keep thinking of things I shoulda said....
IF in the end, this is all chalked up to seasonal allergies (pollens) (check out pollen.com for your area) - then you have options of about 4-5 over the counter antihistamines, prescription antihists, Atopica, steroids, or allergy testing followed by custom injections.
If your baby does have allergies, you really should get her on a grain free high-quality dog food asap - like Kellie mentioned - Orijen, Innova EVO Small Red Bites, Solid Gold Barking at The Moon.
I'm not the biggest fan of Natural Balance allergy formulas bc they contain flax - and I just don't think flax has any business in an allergy food (or, pretty much any dog food, for that matter). Wellness Simple Solutions for allergies do not contain flax
