Want to know how to store your dog food to keep it fresh and safe? Whether you buy your dog's food in bulk or smaller quantities, the way you store it is crucial for maintaining its nutritional value, flavour, and safety. Improperly stored food can quickly lose its goodness, go stale, and even pose a risk to your dog's health.
Keep dry dog food in its original bag, inside a sealed container, in a cool, dry spot in the main part of your home. Refrigerate opened wet food straight away with a lid on, and throw out wet food left in the bowl after about 4 hours (1 to 2 hours in warm weather). Wash and fully dry your container between every batch of food.
Storage is only part of the feeding puzzle, so if you're also wondering how much to feed your dog, our vets have you covered there too.

How do I store dry dog food to keep it fresh?
Keep dry dog food in its original bag, then put the whole bag in a sealed container in a cool, dry spot.
Why does the original bag matter for dry food storage?
- It preserves the flavour: Most high-quality dry food bags have a special oil- and fat-resistant liner. This liner helps prevent the healthy fats and oils in the kibble from escaping. If you pour the kibble directly into a plastic container, the plastic can draw these oils out, causing them to oxidise (go rancid) much faster. This makes the food taste stale, and your dog might even turn up their nose at it!
- It keeps the batch details handy: The original bag contains the batch number and expiry date. This is crucial information to have if you ever need to contact the manufacturer with a concern, or if there is a food recall. If you absolutely must pour the food out of the bag, always snap a quick photo of the batch number and expiry date first.
In practice, the most reliable way to tell dry food has gone rancid is by smell - a stale, slightly oily or paint-like odour rather than the food's normal aroma. If you notice this, it's safest to discard the batch even if it's within the best-before date.
Why do I need to put the dry food bag inside a container?
An airtight container protects the bag from air and pests. Rolling the bag over isn't enough to keep the food fresh and safe. A sturdy, airtight container adds a layer of protection against:
- Air exposure: When fats in the food are exposed to oxygen, they start to go rancid. This not only tastes horrible (making the food less appealing) but can also cause tummy upsets like diarrhoea or vomiting. Always squeeze out excess air and secure the bag with its built-in seal or a bag clip before sealing the container.
- Pests: Critters like mice, storage mites, and meal moths can easily chew through or sneak past a rolled-up bag. A sealed, pest-proof container keeps their dinner exactly where it should be - safe and clean!
To make meal times easier, you can keep a smaller portion of kibble (enough for about a week) in a smaller, sealed container right next to your dog's bowl.
A crucial word of caution: Make sure this smaller container is completely empty and washed with warm, soapy water between batches. A common mistake is just topping up a near-empty container. The older food at the bottom will be oily and can go off, potentially spoiling the fresh food you add on top.
Where is the best place to store dry dog food?
The best place to store dry dog food is a cool, dry spot inside the main part of your home, like a cupboard or pantry, and off the floor.
You need to avoid places with excess heat and moisture. If the food gets too hot, the healthy nutrients can break down, and the fats in the food can start to oxidise.
The simple rule is: Store your pet food in the same kind of environment you would store your own pantry food.
- Avoid the garage or laundry: These areas often experience wide swings in temperature and humidity, which can quickly degrade the quality of the kibble.
- Keep it off the floor: Storing your container slightly off the floor can also help reduce the potential for infestation by insects or rodents.
How do I store wet canned dog food after opening?
Once a can is opened, cover it and put it in the fridge straight away.
Unopened canned food keeps well for a very long time - just check the "best before" date printed on the can. However, once that can is popped open, the rules change entirely.
Opened wet food should be treated just like any human perishable food and must be refrigerated immediately to:
- Minimise exposure to air.
- Retain moisture.
- Prevent bacterial growth.
Tips for refrigeration
- Cover it up: Place a dedicated lid over the can before placing it in the fridge. A snug-fitting can cover is easy to wash, easy to use, and comes in some fun colours!
- Time limit: Once opened, wet food should be consumed within 3 to 5 days. If you haven't used it by then, it's safest to throw it out.
How long can I leave wet and dry dog food out?
Leave wet food out for no more than 4 hours (1 to 2 hours in warm weather), and dry food for no more than 24 hours.
Wet food must be picked up and discarded if your dog hasn't finished it within a few hours.
- The golden rule: It should be consumed within 4 hours.
- Warm weather warning: In warm or humid weather, especially during an Aussie summer, the time limit is much shorter - ideally no more than 1-2 hours.
The high moisture content and protein in wet food creates the perfect environment for bacteria to multiply quickly. Leaving it out too long increases the risk of bacterial contamination, and it can attract flies and other insects that may lay eggs. If your pet has had enough, it's safest to empty the bowl and offer a fresh portion for their next meal.
Dry kibble is far more resilient than wet food.
- You can typically leave dry food out for the day.
- If there is any food remaining after 24 hours, it's recommended to discard it, clean and refill the bowl with a fresh portion.
How do I clean my dog food storage container?
Wash your dog food container with warm, soapy water and dry it completely between every batch of food. Regular cleaning is absolutely essential for maintaining fresh, tasty food for your pup.
The fats and oils in dry food build up on the inside of the container, and that residue will oxidise and turn rancid, potentially spoiling the fresh kibble you put in later.
How to clean it right:
- Wash between batches: Use warm, soapy water to wash the container thoroughly. A scrubbing brush can help remove that oily residue effectively.
- Dry completely: This is the most crucial step. Before you add your next batch of food (whether it’s poured in or the bag is placed inside), the container must be bone-dry. Any remaining water creates a moist, humid environment which is a breeding ground for mould and bacteria, and can quickly cause the food to spoil.
By cleaning and fully drying your container between every refill, you ensure your dog’s meals are always fresh and safe.
