those are not the studies I have read and not been my experience in the 25 years that I have been importing breeding and training,
Now, I will say one thing. there are tons of pet mixed breed dogs out there doing well on grocery store food. Personally, I think the mutts have a stronger system. We lose something in the linebreeding that we do. That being said. I have helped a ton of folks get their dogs off of cortisone shots by taking them off of a grain based cheap dog food. Right or wrong.,tons of GSDs have issues with it. I feed Orijen to all of my dogs,but I will say, that my labs and goldens were on junk from Wal Mart and looked fine when I bought them. so there ya go
It is impossible you read any real studies showing corn (or any grain for that matter) was a primary cause of allergic reactions. They simply do not exist.

This study in Belgium looked at a bunch of other peer reviewed studies and found that all the proteins in grains combined, excluding wheat gluten, totaled just 10%. Corn doesn't even have it own category.
From Dr. Susan Wynn:
"Fallacy 4: Grains cause allergies.
Fact: If dogs have the genetic predisposition to develop food allergies, they can become allergic to certain foods. A recent review of 7 studies indicates that dogs are most commonly allergic to the following foods (in descending order): beef, dairy, wheat, egg, chicken, lamb/mutton, soy, pork, rabbit and fish. In cats, the most common allergens are beef, dairy, fish, lamb, poultry and barley/wheat (in equal numbers), egg and rabbit in equal numbers. I will admit that I’ve seen higher numbers of corn allergy than would be suggested by these numbers, as well, but please note that grains do not constitute the majority of allergy offenders."
Dr. Wynn is no lover cheap foods, I can tell you that:
