Sure am. Do I still feed food with corn to my dogs? Yeah, I do. But I'm not going to deny it's not the best thing for them.
Dogs are carnivores. Corn is non digestible filler. In most dog foods it's ingredient #1 and #2. To me it's clear. End of story.
*shrugs* plus I've seen the difference between a cat and dog fed on traditional dogfood, and a cat and dog fed corn free. The difference was amazing. I am slightly ashamed that my dogs aren't corn-free, but that's just the way things are right now.
