Instructions
Buy only as much food as your dog can eat in a month so the food stays fresh. This is a large bag of food for most dogs, but if you live with a dainty eater, buy smaller bags so your dog always eats fresh food.
Decide what kind of storage solution you're looking for. For small dogs, you can use a wall-mounted or store-and-pour dispenser. Larger dogs need large bins. If you have multiple dog food types to store, or if you have cats or other animals whose food you want to store as well, consider stackable bins as a space saver. As long as you can close the bin against insects and rodents, it can keep the food fresh.
Purchase a dog food storage bin large enough to hold an entire bag of food. You can visit a larger pet store, such as PetCo or PetSmart, to browse through their storage systems. Alternately, you can visit a number of online stores if you have something specific in mind. Beyond the major chains, good stores to begin with are PetFoodDirect and Greg Robert Quality Pet Supplies.
Buy a home storage container, such as a Rubbermaid bin, if you find the animal food specific bins to be too expensive. You can even use a garbage can with a tight fitting lid to store dog food.
Empty the entire bag of dog food into your new storage bin and seal the bin. If you don't use a dispenser, it's helpful to keep a scoop in your bin to dish out the food to your dog.
Stir the dog food when you add new food to make sure the bottom few inches of food doesn't sit in the bin month after month.
How to Store Dry Dog Food
If you buy dry dog food in bulk, the food can go stale well before you get to the bottom of the bag. And storing dog food in the bag can invite mice and insects into your pantry. The solution is to get a storage bin to hold your best friend's food.
