Help finding "right" food for dogs

I would never use Diamond because that company had every single product recalled do to aflatoxin poisoning which points to no real in-house laboratory or biochemist on staff. Diamond's quality can be questioned just because their line of foods does not maintain the same quality across the board like better foods. Some of their formulas contain chicken by-product meal, meat meal, brewers rice, and whole grain ground corn.
   
Two ingredients stick out as either poor or not needed: Fish meal and Salt.
   
All fishmeal is regulated by the US Coast Guard an all fish meal contains Ethoxyquin unless a special permit is obtained. Ethoxyquin was developed by Monsanto originally as a stabilizer for rubber. It's also been used as a pesticide for fruits. This preservative is banned from use in foods for human consumption. It has been linked to thyroid, kidney, reproductive and immune related illnesses as well as cancer.
   
Salt (SoCl) is unnecessary in dog food. The food should contain enough salt naturally without adding it. Albeit salts are needed to sustain life in which case Diamond could have used sea salt which has trace elements of manganese, boron, sulfate, phosphorus, and calcium. One might also ask why they are using potassium chloride along with sodium chloride?

I did not see one thing on their site indicating humane grade & I was looking for that in particular.
   
there must be a wide variety in their foods as I did not see corn or by-products however I agree with everything noles said. guess I should have looked at more varieties.
   
another thing you may want to consider is that if you have large breed puppies - it is recommended by most reputable breeders that they are never given puppy food. they start them out on adult food.

noles - the difference is, she is feeding the "naturals" which doesn't have by-products or corn.
