When I have to, I use Nutro Max (
http://www.nutroproducts.com/maxdogadult.asp )along with a supplement of chopped and sometimes a little steamed but usually raw green beans, brocolli, carrots, or brussel sprouts (Scotties love raw veggies).
Actually, cooking for your pet is the best and is not really more expensive than the processed food

I boil a non-chemical laden chicken (with carrots if you like) until the bones are soft like wet paper and then mix that with chemical free brown rice (I like brown better but some like chemical free white), organic plain yougart (sp.?), the veggies listed above, and a natural vitamen supplement - that will last a week or two and costs about $10 or less. That is essentially what is contained in the dry and wet pet foods, but it is without the preservants. For example, here are the ingredients of Nutro Max Adult Food (from the site above):
Chicken Meal, Wheat Flour, Ground Whole Wheat, Rice Bran, Poultry Fat (preserved with mixed Tocopherols, a source of natural Vitamin E), Corn Gluten Meal, Ground Rice, Lamb Meal, Natural Flavors, Yeast Culture, Calcium Carbonate, Monosodium Phosphate, Potassium Chloride, Choline Chloride, Dried Buttermilk, Dried Kelp, Dried Egg Product, Lecithin, Zinc Sulfate, Iron Sulfate, Vitamin E Supplement, Iron Oxide, Garlic, Ascorbic Acid (source of Vitamin C), Biotin, Vitamin B12 Supplement, Niacin, Calcium Pantothenate, Vitamin A Supplement, Manganous Oxide, Thiamine Mononitrate (source of Vitamin B1), Vitamin D3 Supplement, Riboflavin (source of Vitamin B2), Calcium Iodate, Pyridoxine Hydrochloride (source of Vitamin B6), Menadione Sodium Bisulfite Complex (source of Vitamin K activity), Folic Acid, Copper Sulfate.

Put it this way, dry pet food has a shelf life of years and the canned food sort of does as well, how can that possibly be a good thing?
Having said that, not everyone can or will take the time to cook for their pets, so processed food is their only option. Again, I like Nutromax. I also like Wysong, although my Scotties tended to gain weight on it.
Finally, I know the ingredients above sound a little horrifying, but we as humans eat them all of the time. Just look on the back of any processed food container. Look on the back of the sauce containers like ketchup. You will see some of the same ingredients. And people live until their 90's eating this stuff. So . . . . .
