I don't really care if people feed kibble or not. I know many people don't like raw and there are plenty of quality commercial foods out there. Heck, I feed my dogs partial kibble.
HOWEVER, I don't think advocating Science Diet is 'right' either. And that was the main point of the above post...
Dogs can digest some plant based materials, but not a lot, which is what low quality kibble is jammed packed with.
When the bulk of a dog's diet is full of grain/corn/rice fillers rather than meat, something is truly wrong in my opinion.
