Fellow dog owners - what food do you feed?

[anatess]

I attend the Vet Tech Institute of Houston. Nationally accredited program, and one of many existing schools. My nutrition class isn't geared or biased toward anything other than knowing what it takes to make up a healthy animal diet. They wouldn't be teaching us anything that we weren't meant to pass on to pet parents to ensure their animals' health. There is no emphasis towards any specific food brand or type.

What does your Nationally Accredited Program say about the biological value of Brewer's Rice, Brown Rice, Corn Gluten, and Whole Wheat to a dog's diet? I would think that this program has mentioned that by FDA regulations, a dog food's ingredients list has to be listed according to pre-processed volume, right? Those 4 ingredients are in the top 5 ingredients list of Science Diet.

Also what does the Vet Tech Institute of Houston say about the 24% protein content of Science Diet? Does it think that most of that protein comes from the animal meat that is listed as the first ingredient, or does it think that it comes mostly from the next 4 ingredients?

Wait, even before that... does the Vet Tech Institute of Houston believe this claim from the Hill's website:
Corn is an excellent ingredient because of the benefits it brings to the product. Corn is a highly nutritious ingredient chosen as a source of protein (for muscle and tissue growth), carbohydrates (for energy), fiber, antioxidants (Beta-carotene, Vitamin E, Lutein) and linoleic acid - an essential fatty acid that promotes healthy skin and a luxurious coat.

Hill's uses grades 1 and 2 corn for our pet foods, which are the grades traditionally used for human food products.

While some individuals are concerned about allergies in pets, corn is NOT a common cause of adverse food reactions in pets. Studies have shown that corn causes no more food allergies than any other grain.

Most grains, including corn, are poorly digested before they are cooked. Once cooked, however, they become highly digestible. Corn is also highly digestible, higher than several other grains such as rice, wheat, barley and sorghum.

Does the Vet Tech Institute of Houston teach that just because Corn is finely ground and cooked which makes it highly digestible that that makes its proteins have a high biological value? (In case your school did not teach you this, corn has a biological value rating of 54% compared to muscle meat at 92%).

And, on top of that, does the nutrition class mention anything about the glycemic index of finely ground cooked corn and how that affects dogs?

There are a jillion more moving pieces to this... these are just the main things that are easily "pointable".

I really, honestly, want to know what that school is teaching you about dog nutrition.
