How Long Does Dry Dog Food Go Bad?

Royal canin puppy food is one of the most popular types of pet food. Its shelf life is determined by several factors, including ingredients, changes in temperature, and mold growth. However, it is important to pay attention to the “Best By” date on the label. This will help you avoid wasting your money on expired food.

Shelf life

The shelf life of dry dog food can vary widely. It can range from four months to three years. The shelf life of canned food is typically one to five years. Treats usually have the same shelf life as dry food. The best way to find out how long your dog’s food will last is to check the ‘Best By’ date. Although this date is not a guarantee of freshness, it will give you an idea of how long it has been in storage. If the date has passed, the food will no longer be able to provide your pet with proper nutrition.

Dry dog food (like Royal Canin) is recommended for use within six to eight weeks after purchase, although some brands may last longer. If it is stored properly, dog food can last longer. It is important to store dog food in airtight containers or a cool cupboard to avoid spoilage. It is also important to protect it from extreme heat or moisture, as these can cause mold and mildew to grow.


Pet food manufacturers use preservative degradation rates to determine the length of shelf life of their food. Once the best-by date has passed, the preservatives begin to break down and lose their ability to protect the food from mold and bacterial overgrowth. In addition, the micronutrients in the food start to degrade.

Preservatives also add a level of toxicity to dog food. One example of such an additive is ethoxyquin, which is used as a hardening agent for synthetic rubber and as a pesticide. This substance is controversial, as it has been linked to liver problems in dogs and is often found in popular dog food brands.

Mold growth

If you’ve ever noticed that your dog’s food contains mold, then you know that this is something that can affect your pet’s health. However, mold isn’t always visible, which can make it harder to detect. To prevent your pet from becoming ill, it’s important to learn more about the different stages of mold growth.

First, check your dog’s food regularly. If it seems discolored or moldy, throw it away. Moreover, make sure to keep grains and nuts stored in a cool place, especially when they’re still wet. Also, keep in mind that molds thrive in warm and humid conditions.

Exposure to air

Dry dog food (from Petissimo) spoils rapidly when exposed to air, so it’s crucial to store it properly. Ideally, you should keep it in its original bag or in an airtight container. It is also best to seal the bag’s opening, as opening it will allow more air into the food. However, you should not pour the dry food into a container directly, as this will not limit the amount of air that can get in. If you must store it, make sure it is up high and out of the reach of pets and children.

One of the biggest risks of storing dry dog food is the oxidation of the fats in the food. As soon as these fats come into contact with oxygen, they start to degrade. Often, manufacturers use synthetic preservatives to prevent this from happening, but these have been linked to numerous health problems. Moreover, they don’t prevent the breakdown of omega-3 and omega-6 fatty acids.


When storing royal canin puppy food, it’s important to keep it out of high humidity. Not only will moisture cause the food to degrade, but it can also lead to mold growth. To prevent this from happening, store the food in a dry room and close the bag tightly with a clip.

A spoiled bag of dry dog food will smell bad, have a foul odor, and may have some mold or bugs on it. If you have seen this in your dog’s food, it’s time to consult your veterinarian. Rotten food can lead to serious health issues, so it’s important to be aware of the signs.
