I'll just add this in case anyone from the UK reads this post.
I had the same worries about dog food, so I researched online and came up with an award-winning company based in Britain: Healthy Paws. They are based in Liverpool, but ship (within UK at any rate) for a very very reasonable price £4.99.
The food I buy is Rabbit and Brown Rice dry food for adult dogs. It is excellent holistic food, allergen-free, and containing anti-oxidants, no by-products, omega 3, and health-supporting herbs suitable for dogs. My dog has been fit and well on this. I have fed her this food for about 2 years now, and supplement this with boiled chicken, beef and fish with vegetables like carrot, cabbage, etc.
hey again
it just dawned on me that if your dog is still itching she may have food allergies...
The most common food allergy is chicken, which is unfortunatly also the base of most dogs foods. I would really consider trying the Premium Edge Lamb formula, keep her on it for a good two months to see if she still itches. You can also try adding fatty acids to her diet which will help relieve the itching aswell. A good quality one that is a really fair price is Artic Vigor. You can ask a Pet supply store to order it for you. If you really want to test to see if the itching is food related you should cut out ALL table scraps and remember that treats and cookies may also have chicken ingredients so it's important that you check all the ingredients of anything you give her to make sure there is no chicken. A good hypoalergenic treat is Natural Balance Fish and potatoes.

There is their website. They make REALLY... REALLY good hypoalergenic pet foods and treats but they are a little pricey.
ok! i think thats it, once again, i hope it helps!! =)
Hey
I've added links for 3 very good quality foods that are quite resonably priced. They are not as well known as Iams, Eukanuba, Science Diet or Royal Canin but they are much better quality and at much lower prices. I would check out the websites, i think they all have a "where to buy" button to help you find a location close to you. You can also look online and read different reviews about the foods. Hope this helps =)
