Keeping dog food in the original bag is a safest way to do it. You don’t need a self-sealing bag, just squeeze out excess air as you fold the bag down, and use a big clip. The air in the bag is what causes food to go stale. When you store it in even an air tight container there are several inches of air on top of the food, and more as you use up the food. Home economists say to use a containers that fits the food, in other words, containers that has very little room at the top. Another important consideration when using other containers is to wash the container when you refill food. Oil in dog food has an expiration date, and if it’s left on the sides of your storage container, it can cause the fresh new batch to go rancid. I buy a large bag, and store weekly supplies in the kitchen, so I do use both methods.
