Eye opener about how nutrition of dog food is affected by oxygen. Guess I never stopped to think about it. We certainly will now.

I would like to see corroboration of the allegations in the article. The author has a raw food agenda.

I remember reading 6 weeks somewhere, from someplace I trusted but unfortunately I don't remember where. That seems reasonable to me. Eventually it is going to get rancid and the vitamins will degrade when it's exposed to air. Using the "best by" date once opened is pretty excessive IMO. And I leave dog food in its bag when putting it in a plastic bin. You can feel the greasiness on the bin, and it's a porous surface that's harder to clean properly.

Right - when I sold dog food way back in the 90's every supplier told me to tell the public to leave it IN THE BAG. Iams, Science Diet, Nutro, Cal Natural....ALL of them.

The nutrients are leached out when you dump it into a container and some of the plastic crap leach IN to the food.

That's why the bag has that protective interior material in there.

I have a large container, that has a seal on the lid and the lid locks down with a latch. An entire 30 lbs bag of Taste of the Wild fits easily in the container. And I have two 100+ Malamutes; so the bag is usually empty i about two weeks.

I too use Taste of the Wild and buy four 5 pounds bags a week of different flavors. They are left in the bags, closed with a clothes pin and all put in a storage container.

"If" that is true I have nothing to worry about here, haven't had a bag of food last longer than 2 weeks since the little guy was a puppy....another plus to having a Mastiff...

The author lists six tips to *enhance the life of dry food*...all of them useful and based on common sense. He clearly does not have "a raw food agenda". He may consider a nutritionally complete raw diet superior, as I do, but that alone does not define an agenda. That is merely an opinion.

Oxidation is a well known process that occurs with all foods (and many other substances) at varying rates. Ask any chemist. Or look in your refrigerator. That's like wanting to corroborate the allegation of gravity...there is no need since you see it happening all the time.

If you really want to learn about the oxidation of fats (and other substances) I'd suggest a little Googling. Here's two for you: oxidation | chemical reaction | Britannica.com and Rancidification - Wikipedia, the free encyclopedia

I am not denying that oxidation happens, only whether it is present to a degree that is significant in the usual time that it takes to consume a bag of food.

The link I gave was to demonstrate that dog food manufacturers are aware of the chemistry of the foods they produce.
