I also have a one year old blue heeler who has had the same problem with being itchy since I got him at 6 weeks old. I have taken him to the vet and found that he had a food allergy to the corn and wheat that they use as the primary ingredient in most generic dog foods. Switching him to a primarily meat/vegetable and gluten free diet helped him not be so itchy.
He also has a flea allergy so the only thing a vet will tell you to do about that is don't buy cheap flea drops - go for a reliable brand, and make sure you stay on top of checking them for fleas - especially if they interact with other pets. And don't bother with flea killing shampoos or generic dog shampoo - they only dry their skin more and make the itching even worse. My vet gave me a type of shampoo that is gentle on the skin and made particularly for extremely itchy dogs.
