Hi Everyone,
I already have an appointment for Meg to see the vet on Friday, but I am hoping to gain some knowledge in the meantime so I can be an informed Mommy on Friday.
Meg has really, really itchy skin.

She itches herself all the time, and she bites her paws and legs a lot, too. She hasn't cut or hurt herself with the scratching, but I know she must be very uncomfortable. Her skin (under all that hair) is dry and white-flaky looking. It looks most flaky right after a bath (she gets dried completely) or right after I brush her.
My groomer told me in very broken English (I live in Korea) that I keep her skin too wet and that she will develop a fungus if I keep it up, but she gets a bath every 1.5 weeks and is dried completely, and she doesn't get wet aside from that (except for her chin which always gets wet in her water bowl).
Any ideas what it could be? I have a feeling she has an allergy to something. I don't think it's fungal because there is no hair loss, no sores, and no specifically itchy area. If it is an allergy, how would the vet go about diagnosing it? And what other options are there besides a steroid injection or cortisone injection? I would like to deal with an allergy in a homeopathic way.
If it is fungal, should I have the vet do something besides a skin scraping to diagnose?
BTW, Meg is almost 6 mo old and ~2.5 lbs. She eats a combo of Newman's Own Canned (Chicken and Turkey formula) and Honest Kitchen "Embark" and gets occasional pieces of cooked chicken/beef, cheese, cottage cheese, etc.
