Dog's Food Kibble

How to Store Dry Dog Food Long-Term?

When storing dry dog food long-term, your goal is to remove exposure to light, moisture, heat, and oxygen, as well as make it difficult for rodents to access it. Exposure to these environmental aggressors will speed up microbe growth, causing it to spoil and mold. It’s important that dogs do not eat spoiled food because it causes them to get sick and have serious health complications later on.

Typically, when finding a place to store kibble, you should aim to store it in a tinted airtight container and keep it in a cool, dark place. This will keep the dog food from going stale, and your pup will thank you for it. Some methods for storing dog food are:

Method 1: Store in Original Packaging

This is an important detail that a lot of dog owners overlook. The food’s original packaging is custom-made for one single purpose: long-term storage. In its original packaging, dog food in its typically has a shelf life of 6 to 18 months.

The original packaging also has essential bits of information, like the ‘Best Before’ date and batch code, in case of any type of recall. Or, if you later notice that something seems off with the one you bought, these pieces of information can come in handy when you ask for a replacement or refund.

Method 2: Use Airtight Food Container (Mason Jars)

Prevent dry dog food from getting exposed to the elements by keeping them in airtight containers. Air exposure is the leading cause of pests, fungi, and bacteria getting into the food, which speeds up its deterioration. Mason jars are designed to keep air out of the container and can be made more effective by adding oxygen absorbers. O2 absorbers will remove any excess air still in the glass jar.

If using a mason jar for dry dog food storage, ideally, you should be replacing the dog food within 18 months.

Method 3: Mylar Bags

Mylar bags are food-grade metallic bags that are reinforced by multiple layers of sheets that prevent insects, moisture, or bacteria from entering the food bag. Mylar bags with oxygen absorbers is a popular method for storing dry food items. However, the main downside of using them is that they do not protect against rodents from breaking the bag. Additionally, once you open the bag, you must replace the oxygen absorbers because they will no longer be effective after the bag is opened. When freeze-dry dog food is stored in a mylar bag with oxygen absorbers, its shelf life is up to 25 years (source).

Note: For oxygen absorbers to be effective, the moisture of the dry dog food must be below 10%.

Method 4: Store Kibble in 5-Gallon Bucket

Food-grade 5-gallon buckets are the most effective way of storing dried food items for long-term storage. In the case of dry dog food, it can be stored for up to 25 years. The way to extend the shelf life of kibble for 25 years is by pouring the dog food into mylar bags and adding oxygen absorbers. You would then seal the mylar bag and place it in the 5-gallon bucket. Mylar bags will protect the dog food from bacteria, dirt, moisture, and insects interacting with the dog food. And the food bucket would protect it from rodents as well as environmental aggressors. Preparing food-grade buckets for dry dog food storage will ensure you can continue to feed your dog in any scenario.

Where to Store Dry Dog Food

Try out these handy tips to store dry dog food long-term.

Keep in a Cool, Dry Place

Manufacturers are always reminding us to do this, and rightfully so. Ensuring that the goods we buy are kept out of direct sunlight and moisture ensures they stay fresh for longer.

The moisture-and-heat combo promotes mold growths and bacteria build-up. Needless to say, that’s the last thing we want.

Store in Smaller Containers

No matter how airtight, opening dog food containers will still invite air and moisture into your dog’s food supply. To help prevent significantly reducing the frequency of opening the large-sized container, opt for smaller-sized bins, each about 5 pounds.

First In, First Out (FIFO)

FIFO is the way to go. In other words, the older dog food, or the bag that was opened first, gets served ahead of the others. This will ensure that your dog gets fresh kibble every time.


Keep dog food off the floor. The closer it is to the ground, the greater the risk of moisture exposure.

Not only that, but ants and other pests get easier access if the dog food bag is lying on the floor. Even your dog will find a way to get into the bag. Remember, they’re often smarter than you think.

Use a Scoop & Wash Hands When Handling Dog Food

Whether serving dog food or transferring it from one container to the next, don’t forget to wash your hands first. Otherwise, you risk bringing bacteria into the container. Your pup’s tummy may tolerate small amounts of the bacteria, but it’ll likely cause the kibble to go rancid at a much faster rate.

Use a scoop or cup for good measure. It’s not only sanitary, but you’ll also be able to monitor and control your dog’s diet.

How Long Can Dry Dog Food be Stored?

Additionally, you can also keep your dog’s food stored in mylar bags with oxygen absorbers for up to 25 years. Mylar bags are effective against most external threats, with the exception of rodents.

Dry dog food can be stored in a food grade 5-gallon bucket and stored for up to 25 years. As mentioned earlier, brands like PetPrep and Pet’s Banquet specialize in making packaging for long-term storage.

How to Tell if Dog Food has Gone Bad

Below are some surefire signs that dog food is no longer fit for consumption. If you notice any of these, seal the package well and throw it out immediately.

  • Formation of black, green, or white mold spores
  • Discoloration, especially if it turns green or black
  • Emitting bad odor
  • Your dog won’t go near it

If it happens by chance that your dog ingests moldy food, he could be at risk for food poisoning (source), which can have the following symptoms:

  • Vomiting
  • Diarrhea
  • Tremors
  • Rigid limbs
  • Restlessness
  • Disorientation
  • Seizures

If your dog shows any of these symptoms, contact your veterinarian immediately.

Why Proper Dog Food Storage Matters

You always choose the kibbles with the most nutritional benefits in the market for your pup. That’s why it’d be a waste to find out later that it’s gone bad just a month after purchase because it wasn’t stored properly.

Storing food properly is important because a simple oversight can be lethal and cause serious health issues. For this reason, you should understand the dangers of feeding your pooch food that’s gone bad if you neglect proper dog food storage practices.

Here’s why:

  • Prevents bacteria and fungi contamination
  • Prevents mold mites or shrank
  • Protects from toxicosis (source)
  • Protects from mycotoxins (source)
  • Retains the food’s flavor and ideal texture
  • Prevents the loss of nutrients
  • Slows down food degradation
