Thanks for posting that Boo's Mom..that's a good informational site. I signed up for e-mail alerts a couple of years ago from them.
When I got my first Gangsta years ago I started feeding Eukanuba. I seemed to be a good food, not cheap, and my dogs did fine on it. I began to notice over time that the dogs didn't do as well on it, coats were dull and energy levels were low. Then came the huge dog food recall of several major brands and in researching dog manufactures I found that the majority of them are all processed in the same plant, so cross contamination is easy. This gave me incentive to research the companies that made dog food and the process. I was pretty horrified at what I found overall.
I came up with a brand called Innova. It was a small family owned company that had their own processing plant and used human quality ingredients. I felt comfortable with this and began buying it. Because it was a small company with limited distribution, it was not easy to find off the shelf, so I ordered it online. It was a good food and the Ganstas did great on it....Then, they sold out to Proctor and Gamble and of course, they assured their customers that nothing would change. I was very skeptical, but continued to feed it until two of the Gangstas that were on it came up very sick.
The vet could find no specific reason for all the vomiting and diarrhea, and I suggested maybe the food since Ohno wasn't on it and he was fine. He agreed I may have gotten a bad batch. I called the company and sent back a sample, along with the lot number. Of course, they disavowed there was anything wrong with it.
Back to the drawing board of searching out a replacement and I came up with a brand called Precise. They are a small company in Nacadoches, Texas that uses human grade ingredients. Again, because of the small company and limited distribution, I have to buy it online. That's really easier for me since it is automatically delivered to my doorstep every six weeks.
I feel compelled to research these dog food companies out because I feel like I dodged a bullet with that major recall. Lesser recalls are happening constantly, and Boo's Mom's website keeps me alerted. They do this not only for dog food, but cat food and treats as well.
Here is a good article, not for the squeamish though, about what actually goes into processed pet food:

There are no easy answers to making sure commercial dog foods are safe to feed your pet, but short of becoming a canine or feline nutritional expert, buying ingredients and cooking meals for your pet, it's what we have to work with. Quality dog food is not cheap, and there are no guarantees after doing all the research that your dog food will not end up on a recall list tomorrow.
Also, I will add that there are many proponent of feeding a raw diet to dogs. I really don't know the if there is proven nutritional validity to this, but I do feel this is unsafe, both for the dog and the human handlers as salmonella and e-Coli can be spread on uncooked meats. It is very hard to maintain an environment disinfected from this when a dog is chewing raw bones and meat, and possibly getting it on the floor, paws, face, and wherever they may lick after eating. This can be especially dangerous for small children and people with compromised immune systems.
One other thing I will ad is that it is surprising how little vets actually know about dog nutrition. They will push the brands they sell on the shelf because they get nice incentives from the dog food companies to do so, but they have little knowledge of how they are made, or what's actually it them. Some of the high priced prescription diets sold exclusively by vets are the nutritionally worst on the market.
