My German shepherd dog has very bad skin problems and allergies. We use Pets 1st. I think that they are the best dog food company ever, even though I hate dog food lol. They don't use corn flour (which is what most dogs are allergic to) and use human grade meat, real vegetables, natural preservatives (only vitamins c and e) and other great things. My dog's skin is great now.

The food is quite expensive, probably about 40 dollars a bag for a small dog, but the food lasts six months.

Here is the addy for the pets 1st website

Good luck!
