I do think Abby might have allergies. I just switched her food to Canidae and NV raw. She hasn't had any of the raw yet, as a matter of fact, today is the first time she's even had the new kibble. So, I don't think it's the change in her food, but maybe she's still having some reaction to her old food or it's outside type stuff, mold, pollen, etc.. Her eyes will water a lot at times.
Just now while I was holding her on my lap, it sounded like she threw up and swallowed it.
Now she's resting peacefully.
I guess a call to the vet is in order.
