Most of what dog and cat food consists of, especially the dry stuff, is a hybrid corn. Corn is bad for the dog and cat. The corn industry uses a great deal of toxic and non-renewable resources from fuel to fertilizer, and from a plastic coated bag to a metal can for that corn to make its way to the shelf and food factories. My wife and I have been making our own dog food (which does not contain corn) for a few months now and it actually costs us less than buying regular dog food. The dogs like it seem to be healthier, we don’t have the extra trash from the dog food bags/cans and we can buy ALL of the ingredients (except the oats or rice) locally. its extra work, but very possible.
