Does Dog Food Go Bad?

Just like human food, dog food can go bad. Even dry dog kibble can start to grow mold or microbes, which could make your dog sick.

Over time, dog food can also:

  • Lose nutrients: Some nutrients are sensitive, so old dog food won’t be as nutritious as fresh dog food.
  • Get infested with pests: Pantry pests like moths and weevils especially love dog kibble. These pests can then infest the rest of your food supply. Your dog might not mind eating insects, but I certainly don’t enjoy them in my food! Read about how to keep insects out of your food supply.
  • Go rancid: The fats in the dog food will go rancid. While rancid food won’t necessarily make your dog sick (not like bacteria or mold will), it develops a nasty taste. Your dog might not want to eat kibble after it’s gone rancid.

How long does dry dog food last?

Unopened and in its original packaging, dry dog kibble will last approximately 6 to 18 months.   Dog food with lots of preservatives will last longer than higher-quality dog food with natural ingredients. If stored in an airtight container in a cool place, dry dog food can last a couple years.   If stored with oxygen absorbers and kept cool, dog food can last over 5 years without going bad.

How long does canned dog food last?

Most canned dog food has a “best by” date of two years after manufacturing. However, most canned food will last indefinitely, including canned pet food. For more, read this article about how long does canned food last?

Because it never goes bad doesn’t require any special storage, canned dog food is the most straightforward emergency food for your dog. However, canned food is pricier and takes more space than dry kibble. For this reason, it doesn’t make sense for most people to store canned food for their pets.

How to Store Dry Dog Food Long-Term

The best way to store dog food long-term (more than a year) is to put it in an airtight container with oxygen absorbers.

This creates an environment that is almost entirely free of oxygen. Microbes and insects can’t survive without oxygen. Fats won’t go rancid, and nutrients won’t break down as quickly without oxygen. It’s also essential to keep the dog food somewhere cool and safe from rodents.

Instructions for storing dog food long-term:

  1. Put it in a Mylar bag. You can also use other airtight containers like Mason jars, but Mylar bags are the most convenient for storing large amounts of dog food long term.
  2. Add oxygen absorbers. The amount of OAs depends on the size of the Mylar bag.
  3. Seal the bags: Don’t forget to label them!
  4. Put it into a bucket with a lid. This will keep the Mylar bags safe from pests like rodents.
  5. Keep somewhere cool. Even when stored with oxygen absorbers, fats will still go rancid in hot temperatures.   Try to keep the dog food somewhere cool.

Can I store dog food in 5-gallon buckets or plastic containers?

Some people simply dump bulk dog food into 5-gallon buckets or other large plastic containers. Stored this way, dog kibble won’t last much longer than in its original packaging. There is simply too much air in the container, which will cause the dog food to go bad.

In some cases, the dog food might go bad faster in a plastic container as scratches can become breeding grounds for mold or bacteria.

Also, don’t be surprised if you end up with an insect infestation if you store dog food this way.   Often, insect eggs are already in the dog food when you buy it – especially if you buy dog food in bulk. The insect eggs eventually hatch and infest your entire home. Moths and weevils are surprisingly good at getting through even “airtight” lids!

If you still want to store dog food in plastic containers, make sure you:

  • Use plastic containers with good lids. Mason jars also work, but most are too small for storing large amounts of dog food.
  • Take steps to kill insect eggs in the dog food, such as by freezing the food for a few days before storage.
  • Rotate through the dog food within 1-2 years. Make sure you label the containers with the date to rotate in the correct order.

What about vacuum-sealing dog food for long-term storage?

Vacuum sealing removes some of the air from the bag, thus helping the dog food last longer. However, vacuum sealing does not remove all of the oxygen. On top of that, vacuum sealer bags aren’t completely airtight. They will eventually allow some air and moisture into the sealed bag. For this reason, vacuum sealing is NOT a good long-term food storage method.

Should I keep dog food frozen?

Dog kibble will stay fresh indefinitely when stored in the freezer. However, freezing dog food generally is not a good long-term storage method. Dog food has a powerful odor. It doesn’t take very long until everything in your freezer starts to smell like kibble. To prevent this, you have to repackage the dog kibble in airtight packaging.

If you are already repackaging the dog kibble, it probably makes more sense to just put it in Mylar bags with oxygen absorbers. Packaged that way, dog food doesn’t need to be kept frozen and will last for years without going bad.

Another Option: Freeze Drying Dog Food

Freeze-drying is a process that removes moisture from food, thus allowing it to last for a very long time.

Freeze drying machines are expensive, but you can freeze dry wet dog food if you have one. You can then store this dried food in Mylar bags with oxygen absorbers. Stored like this and kept cool, the dog food might last well over 10 years.

Some brands sell freeze-dried dog food, but it is primarily costly raw food that isn’t suitable for long-term storage.

  1. Everything on this website is so thorough and helpful! Thank you for what you all do! What thickness of Mylar bags do you recommend for storing dog food (sealed Mylar bags will, per your recommendation, go inside a 5 gallon food bucket)?

    Reply
    • 3 to 4mm bags should be good for dog food. I don’t like using thicker than 5mm bags because they are actually pretty sharp and it’s easy to cut yourself!

  2. I have human freeze-dried food stored for long term so I assume I can store freeze-dried dog food also. Honest kitchen has a freeze-dried food.

  3. Is there a dry dog food that has less than 10% moisture? You’re not suppose to store any food (most dry dog food) with moisture content above 10%, with oxygen absorbers due to botulism. I’ve been trying to find one with moisture below 10%, but I can’t seem to. Any idea which brand offers this? I found a cat food with below 10%, but still no dog food. Thanks

    Reply
      • It actually requires approx. 35% moisture for botulism to grow. The 10% recommendation is to play it safe. You could always dry out the dog food to reduce moisture levels (in a dehydrator or oven) — but warning that your entire home will probably smell like dog food if you do that. Best to dry it in a garage or other outdoor space.

        If that’s too much work and you are only stockpiling a few months worth of food, you can just rotate through your dog food supply.

  4. So my dog is on a raw diet, and my bug out bag has freeze-dried raw food for her in it with an expiration date 2 years out. It was really important for her gut health to go raw, and I don’t think she’d be able to switch back to kibble without health issues. What are my options? Would DIY freeze-dried raw food last longer than the store-bought stuff? We currently use Instinct and Acana brands, which supposedly last a couple years. Can I store them the same way?

    Reply
    • Yes, you can store them the same way as other freeze dried foods. But you’ll need to get food which has a low fat amount, since fat will go rancid in high temperatures (even if it is packaged in Mylar bags with oxygen absorbers). You might want to look into buying a freezer drying machine. They are large and very expensive, but it will probably end up cheaper for you in the long run since you’ll be able to make your own dog food.
