You are so right about the grains fed to the cows. 3 years ago I started feeding my pups real protein based kibble and not the Corn-based Ol' Roy crap Wal Mart. 50% protein, lots of fats, and NO GOD DAMN CORN!!!
What prompted it was that I had a beautiful Alaskan Malamute who I had to put down for no other reason then he became too fat and damaged his hips over the years. I could never get his weight under control. I never target his type of food...just his portions. He got so much exercise and I really limited his portions. It didn't matter. Eventually the years of extra weight caused some serious hip issues. It pains me because he had all his bearings and senses still and he was only 8. I have no doubt that I literally fed the boy to death.
Ironically, at that point, I was about 270 lbs. I should have put myself on the same primal diet my dogs went on.
I guess grains do kill.
