Corn is not a bad fiber source. It should not outweigh the meat content of a kibble, however. The problem with it is many food brands use it as the #1 protein ingredient or else use Corn Gluten Meal, which isn't even edible to dogs (its a type of chicken feed). Corn's protein digestibility is around 50%, so it's the worst source of protein to use, and very inferior to meat.

Note that both studies are talking about Corn as a fiber source. No good dog food uses it as a protein source. I think some people get confused to think no dog food should use it at all. Like any fiber, it should not be the major ingredient.
The dogs that won the Iditarod eat a fish meal and corn-based dog food.
Regardless, Eukanuba isn't all that great. But then, you have to forgive a vet for being ignorant when it comes to dog food, since most of them are. Her comment about by-products would be true if there was any actual quality control of by products. Technically, the best 'by products' would be mostly good organ meats, but the current legal definition allows anything with no way to tell how much of the by product is actually useful vs garbage. She puts too much faith in the food companies to actually use quality stuff, which is natural seeing as how she probably got he nutritional training from them.
Being snobby though, is something I wouldn't tolerate either in my vet. I want a vet who won't treat me like I'm an idiot.
