Going green doggy and saving money?

We are struggling right now with the economic situation and we need to cut back on expenses. Which brand of organic food is good but inexpensive? I was wondering if Trader Joes brands its food via another big company or if they have their own food. For instance I know that Trader Joes organic milk brand is actually Clover Milk and many of their specialty products are local boutique companies but they sell the products for half the price....
