    It's wonderful that there are so many high-quality, balanced diets available for our dogs today! 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. We've all seen clever dog food containers on the market, but what's the best way to use them? Learn the essential steps to keep your dog's tucker tasty, fresh, and safe, ensuring they get the most from every meal.

    How to store dry dog food for maximum freshness

    The golden rule for storing dry dog food is simple: keep it in a cool, dry place, sealed tight, and away from pests!

    Why the original bag matters for dry food storage

    Surprisingly, the best place to keep your dog's dry food is actually inside its original bag. Then, you simply place the entire bag inside a sturdy, sealed container.

    Here's why keeping the food in the bag is essential:

    • 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.

    Why you need to put the bag in a container

    While the original bag is great, it needs backup! 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!

    Pro tip for easy feeding

    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.

    Here is the rewritten section on where to store dry dog food:

    Where is the best place to store dry dog food?

    It’s tempting to tuck that big bag of dog food away out of sight to reduce clutter, but where you store it is just as important as how you store it!

    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.

    Ultimately, a cool, dry spot inside the main part of your home - like a cupboard or pantry - is the ideal location to keep your pup's kibble fresh and tasty.

    How to store wet canned dog food after opening

    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:

    1. Minimise exposure to air.
    2. Retain moisture.
    3. Prevent bacterial growth.

    Quick 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 5 to 7 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?

    Wet Food Time Limit

    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 Food Time Limit

    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.

    Cleaning your dog food storage container

    Regular cleaning of your dog food storage container is absolutely essential for maintaining fresh, tasty food for your pup.

    Why cleaning is crucial:

    Dry food contains fats and oils that can build up on the inside of the container over time. If this residue is left, it will oxidise and start to smell and taste rancid - potentially spoiling the fresh kibble you put in later.

    How to clean it right:

    1. Wash between batches: Use warm, soapy water to wash the container thoroughly. A scrubbing brush can help remove that oily residue effectively.
    2. 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.

    FAQs

By following these simple vet guidelines for proper storage - using the original bag in a sealed container, refrigerating opened wet food, and regular cleaning - you ensure your furry friend is always getting the most nutritious and delicious meal possible. A happy dog starts with a fresh bowl!
