Undecided Question

My dog has pink, itchy, dry skin?

I have a border collie who's hair is naturally long, but since the begining of winter she's been scratching a lot and her skin under her white fur has been bright pink. She's had really bad dandruff as well, and her long hairs from her tail, backs of her legs and arms are thinning and falling out. What can I do to help her dry skin? I don't care if she looks like patchy the freak dog, I just want to stop her itching. It's obvious it bothers her because she'll jump and scratch herself often.

I know it's not ticks or fleas because I check her skin daily.
