How is she with fish? Fish is generally the best for skin due to the excess of omega 3 and 6. Alternatively, you could use a potent fish oil supplement - I'm not sure what's near to you but in the winter months, I supplement Finnegan with a bit of Ascenta and it does wonders. He's also on a fish kibble right now.
If she might like fish, I'd try Acana Pacifica, Fromm Surf & Turf or another grainfree fish formula.
ETA: I just saw your other thread on the health forum. Is she itchy everywhere? Is she chewing her feet? In most food allergy cases, itching is centered on the base of the tail and the feet. She may just have dry skin, have you checked her for flakiness?
She doesn't seem to like fish. I had her on a salmon formula as a puppy, but nothing ever compared to the chicken based formula that she was on as a puppy.. she loved the stuff!
GPF was out of Acana Pacifica which was what she had originally recommended but we ended up going with Go! Chicken + Turkey which looks pretty promising and apparently she ate a fair bit out of the bowl when we got home. It has coconut oil as an ingredient as well as salmon oil and deboned trout.

I was pretty darn impressed with their customer service and the knowledge, but from what I've seen, Global Pet Foods is good with that kind of stuff. They just adored Cali and gave us a free sample of the Go! just in case she didn't like it so we could return the bigger bag.
And NinaB, I'd be so tempted to feed raw if my mom would allow it. That's where she'd put her foot down, I'd imagine.
She already tolerates me buying bully sticks, etc and spending more money on Cali than anyone else.. she'd think I was crazy for suggesting raw. Although, I do want to feed my dogs raw once I'm out of university and have my own place.
