Check with your local pet supply shop, because some brands offer frequent buyer programs for their dry lines, which can be a big help if you're going through it. Natural Balance, Petcurean, and Nutram all offer grain-free recipes and frequent buyer programs. Nutram seems the best. Their dry food is pretty reasonable and contains no potatoes, which makes it different from a lot of foods on the market. Petcurean is expensive either way, and Natural Balance requires you to buy two more bags than the competition before you can redeem your free bag. Some pet supply stores also offer discounts on cases of cans, so its worth asking!
