Try Baby Oil on the itching area where the dog is chewing fur. Aloe Vera is another potion to try, just break off a bit of the plant and touch the broken end juice onto the itchy area.
Maybe bird mites, my dog always used to get itchy when I took her to the river water ramp where there were quite a few ducks and assorted bird life.
Maybe look at diet, especially dry dog food, I found that my dog got an itchy bum with a certain brand of dog roll, which was dry and didn't need refrigeration, presumably the preservatives were the cause.
