RAH...I appreciate your thoughts. I am not on the anti-GMO bandwagon, either. Here's what I know...when my dog ate Brand X(very well known and trusted manufacturer), he'd not keep that grain-based food down. He lost 15 pounds over three months. I thought he was over-eating. We sheared him, I saw how thin he really was and thought something was physiologically wrong. Took him to the vet for tests...all tests negative. He asked me what I was feeding. I told him. He said, "That's the problem. That food is incompatible for your dog. Go buy this food...and let me see him in a month."
He also told me to give him a Prilosec every day for about a week, so I did.
Now, three months later, he's regained his weight, plus some.
