Kibble 101: Are You Storing Your Dog’s Kibble Safely?


When it comes to mealtime, do you fill your dog’s bowl with kibble? Despite many puppy parents switching their canine companion to a fresh food diet, there are still a lot of people who rely on kibble. It can be more convenient and more affordable. If your dog chows down on crunchy kibble as his main meals, there are some important tips to consider. Let’s start from the beginning – in the pet store.

How To Buy Kibble

I know what you’re thinking: “Buying kibble is a no-brainer. I just have to swing by the pet store, grab a bag of food, hand over the cash, and I’m good to go.” On the surface, yes, that’s true. But, let’s back up a bit. Here are some things you should consider when picking out a bag of pet food:

  • Size Does Matter – If you have a 5-pound dog then you don’t need a 40-pound bag of kibble. Rather, only purchase bags of food that you can use up within about one month. I know larger bags appear cheaper when looking at the sticker’s unit price. But, at the end of the day, the small savings aren’t really worth it because the longer a bag of kibble sits open, the fewer nutrients it retains. Plus, the greater the chance of contaminants. Keep reading and I’ll tell you why below.
  • Expiration Date Check the expiration date and try to choose a bag that has the latest date. The further away from the expiration date, the fresher the bag of kibble (as long as the bag is sealed and totally intact). The expiration date only counts towards a bag that is sealed and intact. So don’t buy any ripped or torn bags. Once the bag is opened, the expiration date is no longer accurate. As soon as you open the bag, air and oxygen hit the kibble and the oxidation process begins. Oxidation is where a chain of chemical reactions oxidizes the fats and turns them rancid. Rancid fats decrease the nutritional quality of the kibble, as well as making the food potentially toxic. That’s why it’s so important to store kibble properly. The least amount of oxygen that gets to the kibble, the longer it will last.

The Effects Of Rancid Fats In Kibble

As fats in kibble turn rancid, the nutritional value decreases. If your dog continues to eat this food, his tummy may get full, but he won’t get the nourishment you had intended. Rancid fats reduce the protein content, vitamins, minerals, and antioxidants of the kibble.

Additionally, rancid fats can also make your dog sick. They’ve been known to cause gastric upset, diarrhea, cancers, liver disease, heart disease, and a host of other health problems. According to Dr. Karen Becker, pet food formulator Steve Brown says: 

“Feeding rancid fats is worse than feeding no fats at all.”

How To Know If The Kibble Is Rancid

Rancid fats have a distinct smell. Many describe it like plastic. The best thing you can do is get familiar with how a fresh bag smells when you bring it home so you’ll know what it should smell like. I must admit, I’ve never smelled a bag of kibble that made me say “Yum.” But I am familiar with what’s normal and what it’s supposed to smell like when it’s fresh.

It’s also a good idea to inspect the kibble for anything that looks off-color, moldy, or that you would consider out of the norm. Keep an eye on your pooches stools and be aware that spoiled food may cause diarrhea.

Keep The Kibble In Its Original Bag

The original bag is designed specifically to help keep the food fresh for as long as possible and to safeguard it from the effects of moisture and oxygen. Higher quality kibbles use higher quality bags in their packaging.

The bag also has the identifying manufactures information such as UPC codes, Barcodes, ingredients, etc., that you will need if there is a recall of any kind.

Never leave the bag open to the air. Roll or fold down the top of the bag while pressing out as much air as you can. Use a clip to hold it in place. Remember: In the case of kibble storage, the goal is to keep the air and moisture out.

Want To Store Your Kibble In A Plastic or Tin Container?

A lot of places sell plastic or tin containers, advertising them as a great way to store kibble. If you want to use one of these containers, that’s fine. But there are some things to consider: 

  1. Make sure the container is an airtight food grade container.
  2. Don’t just pour the kibble into the container. Rather, keep the kibble in its original bag and then place the entire bag into the container. Why? Well, the fats from the kibble can seep into the walls of the plastic container and contaminate the kibble as it’s turning rancid.
  3. Every time you change to a new kibble bag, remember to thoroughly wash and dry the storage container just in case there is any fat residue left on the walls. You don’t want to risk contaminating a new bag of food.

Finding The Right Home For Your Dog’s Kibble

Store kibble in a cool dry place – preferably in the pantry. You never want to store your kibble in places like the garage or basement where the temperature and moisture are not as controlled. Kibble stored in a garage or basement is also more prone to contamination by rodents and mice.

When It Comes To Filling Your Dog’s Bowl …

If you free-feed your dog then make sure to only fill the bowl with enough kibble for one day – don’t let it sit out for multiple days if your dog doesn’t finish it. As I mentioned above, when oxygen hits kibble, the nutritional value decreases. 

Additionally, don’t force your pooch to eat what’s in the bowl if he’s turning his nose up to it. If your pooch always eats his kibble and all-of-a-sudden doesn’t want to (as long as he isn’t sick, of course) then he may be smelling that something is not right with it. His sense of smell is much keener than yours, and he may detect that the food has spoiled. Don’t just leave it there for days on end figuring, “Oh well, he has food.” Instead, it may be time to get a new bag of food.

Extra tip: Don’t forget to wash his food bowl daily to remove any residue that’s been left behind.
