Hi again Jonathan-
I’ve heard a lot of things about pet food storage as well. I work at a small pet boutique that mainly carries natural dog foods with natural preservitives. If we catch a bag with a hole in it, even a tiny one, it gets damaged out and put on the return shelf because once air has started hitting the food the fats start going rancid.
Most of what I’ve heard about what size bag to buy depends on how fast you go through the food. I can buy 5lb or 15lb bags for by 68lb dog and I store them in a Gamma Vittles Vault air tight container. A 5lb bag will last slightly under a month and a 15lb bag will last me well over a month for him. I don’t buy the largest size bags anymore as I switch foods more frequently than that size bag would allow. That being said a small breed dog or toy breed dog is not going to eat a 30lb bag before the food would start to go rancid, so it would not be smart to buy such a large bag for a small dog. That size would be fine however for a large or giant breed dog that was not eating canned food as well (my dog eats canned so my dry food lasts longer).
