My biggest issue with dog food (most dry & canned), is the vitamin premix. If the ingredient label contains a list of vitamins & minerals, it is EXTREMELY likely that those vitamins are sourced from China. China is contaminating products with melamine which is why dogs are becoming ill and dying. It is NOT salmonella. Dog food manufacturers are not required to disclose the sources of ingredients. ONLY where the product is manufactured. I stick with a raw food diet. i wrote extensitely about these issues on my website essentiallydogs.com. You can type keywords on the website search bar. Raw, salmonella, and FDA are good keywords to search.
