Have you changed anything in the house recently--using a different laundry detergent? Using fabric softener--or a different brand of fabric softener. New carpeting? Had the carpet professionally cleaned? Did they put on one of the products that is supposed to repel dirt?
All of this kind of stuff can be something your dog is sensitive to or downright allergic to. Cold weather is dryer--sometimes something as simple as a couple of water containers around the house will raise the humidity (I remember my grandmothers house always had a pan of water on one of the out of the way registers--I used to regularly spill it--that got me yelled at by everyone).
I'd definitely start fish oil--I use capsules which I buy at Costco--a bottle of 400 is still under $10 and they have it on sale about three times a year for $6 or $7. I prefer the capsules to liquid--they are less messy and once opened the liquids oxidize quite quickly and are not as effective.
But along with this stuff I'd also check in with my vet and make sure she isn't harboring some sort of skin parasite and get her checked to see if she has scratched herself so much that she now has a skin infection. If that's the case she may need antibiotics to clear the infection before she'll heal.
And finally Meadowcat is right on about environmental allergens being much more present in houses that are closed up in cold weather. Mold and dust mites (natures little cleaner uppers of skin, dander etc) both are culprits when it comes to activating allergies.
