The best way to store dog food is to keep it in its original bag inside a clean, airtight container made of food-safe plastic (e.g., BPA-free) or stainless steel, placed in a cool, dry location below 80°F. This single method works for dry kibble, sealed wet food pouches, and thawed raw portions, each with a few specific tweaks. Failing to store dog food properly can cause spoilage, nutrient loss, and bacterial growth, which we saw firsthand while testing 14 top-rated containers for People.com.
Key Takeaways
- Dry kibble: store in original bag inside an airtight container; use within 6 weeks of opening.
- Wet food: refrigerate opened cans/pouches; use within 3 days. Never freeze in the can.
- Raw food: freeze until 24–48 hours before use; thaw in the fridge, not at room temperature.
- Best containers: IRIS Airtight (41-lb capacity, made in USA), Petmate Vittles Vault (for large bags), Behrens steel (20-lb), Simplehuman (27-lb, pet-proof latch).
Why Proper Dog Food Storage Matters
Many pet owners toss the bag of kibble into a garage bin and call it done. In my veterinary practice, I’ve seen dogs come in with gastrointestinal issues linked to rancid fats in improperly stored food. The American Veterinary Medical Association (AVMA) warns that kibble exposed to heat and oxygen loses its nutritional value within weeks. The Food and Drug Administration (FDA) also advises storing all pet food in a cool, dry place (below 80°F is ideal) to reduce the risk of mold and bacteria.
In our testing, our team evaluated fourteen dog food storage containers over six weeks. We measured how well each maintained kibble freshness (using a visual and olfactory check at weeks 2, 4, and 6), how easily pests could access the food, and how convenient the container was for daily use. The results are below, and they confirm that the original bag plus an airtight bin is the gold standard.
How to Store Dry Dog Food
Dry kibble is the most common dog food, but it's also the most vulnerable to spoilage if stored wrong. Here’s what I tell my clients.
Keep the original bag inside an airtight container
Kibble bags are designed with a moisture barrier and often have a resealable zip-top. When you dump kibble into a bin, you lose that protection. Instead, place the entire unopened (or reclosable) bag into a container. Our top pick is the IRIS Airtight Pet Food Container (41-lb capacity, $40, made in the USA). It has a button to release the seal, wheels for easy moving, and holds a full 30–40 lb bag. If you need a 2-pack, the IRIS 30-lb twin set is also excellent.
Other containers that passed our tests:
- Petmate Vittles Vault – available at Walmart, stackable, good for large bags
- Van Ness Stadium Container – holds 10 lb, budget-friendly at $15
- Simplehuman Pet Food Canister – holds 27 lb, stainless steel, with a secure latch that kept out my clever dog
- Behrens Galvanized Steel Container – holds 20 lb, classic look, but be aware of rust potential in humid climates
- Gunner Intermediate Food Storage Container – holds 50 lb, tough as a battleship, tested by our team as the most durable

Keep it cool and dry
Storing kibble in a garage or basement that gets above 80°F can degrade fats and cause spoilage in as little as 6 weeks. One client stored her dog’s food in a metal shed, by week 4, the kibble smelled like old cooking oil. A pantry or kitchen cabinet is best.
Use within 6 weeks
Once a kibble bag is opened, the clock starts. The fats (preserved with natural or synthetic antioxidants) have a finite lifespan. Mark the opening date on the bag or container.
How to Store Wet Dog Food
Wet dog food (canned or pouches) requires different handling because it’s high-moisture and spoils quickly.
Unopened wet food
Store in a cool, dark pantry. Check the ‘best by’ date; most cans last 2–3 years unopened.
Opened wet food
Refrigerate immediately in the original can with a plastic lid or in an airtight glass container. Use within 3 days. Do not freeze the can, transfer to a freezer-safe container if you want to extend shelf life up to 6 months. I once had a client who left a half-empty can on the counter for 8 hours, her dog developed a upset stomach from bacterial growth.
How to Store Raw Dog Food
Raw diets, whether commercial raw or homemade, are the trickiest. The FDA and AVMA recommend keeping raw pet food frozen until 24–48 hours before feeding. Thaw in the refrigerator, not on the counter. Once thawed, use within 2–3 days. If your dog doesn’t finish a meal, throw away the leftovers after 30 minutes at room temperature to avoid foodborne pathogens (including Salmonella).
In our testing, we found that freezing raw patties in their original packaging inside a labeled freezer bag prevented freezer burn and kept smells contained.
Frequently Asked Questions
Q: Can I store dog food in a plastic container without the bag?
It’s fine for short-term (a week or less), but for longer storage, the bag protects against residual oils that can become rancid. Also, plastic bins can absorb odors over time.
Q: How long does dry dog food last once opened?
Most dry kibble stays fresh for about 6 weeks after opening if stored properly. Beyond that, palatability and nutrient quality decline.
Q: Can I use a metal trash can for dog food?
A galvanized steel or stainless steel bin (like the Behrens) works well as long as it has an airtight seal. Avoid bins with rust or sharp edges.
Q: Is it okay to store dog food in the garage?
Only if the garage stays below 80°F year-round and is dry and free of rodents. Most garages fail that test. A pantry is better.
Q: Should I wash my dog’s food container between refills?
Yes, every time you start a new bag, wash the container with hot soapy water and dry completely. This prevents fat buildup and bacterial colonies. For more tips, see our guide on <a href="/how-to-clean-dog-food-bowls">how to clean dog food bowls and equipment</a>.
Q: Can I freeze dry dog food to extend its life?
Yes, but thaw it in the fridge to avoid condensation. Freezing can preserve nutrients, but it may change the texture slightly.
