I don't knowingly feed my dogs low quality food.

I don't need to research, I've done that, extensively.
Companies like Iams, Purina, etc. are out to make money. Thats why you see the funny commercials and the beautiful bags. In order to make up for that advertising they have to put lower quality ingredients into the food. They NEVER use organic ingredients, they ALWAYS use fillers, etc. And the whole "puppy formula" thing is a scam in itself.

Corn meal & corn grits, brewers rice (the lowest quality of rice), grain, and barley.... thats a heck of alot of grains and carbs you dog DOESNT NEED. Where does it go? Poop. Lamb meal, that's not bad. I'll give them that one. Natural chicken flavor, what the heck is that? Dried egg product? Another what the heck. How about fresh eggs from pheasant or quail? Salt? Just plain old iodine filled salt? Why not sea salt? Brewers yeast - again, anything brewers is low quality and for alot of breeds yeast = yeast ear infections. Gross!!!!
I'll compare it to my current food.

If you can knowingly feed purina or whatever it is you feed, great for you. I prefer to give my dogs something healthier since they can't chose for themselves.
