Factors that Affect the Shelf Life of Dog Food

Alright, let’s talk about the factors that can affect the shelf life of your dog’s food.

Regarding the shelf life of dog food, there are several factors to consider.

Notably, dry dog food typically has a longer lifespan than wet or canned food varieties. Additionally, homemade recipes have the shortest shelf life and should be consumed sooner rather than later.

In addition to packaging and storage methods, the ingredients used in dog food can also impact its shelf life. Certain ingredients may cause faster spoilage than others.

It’s essential to remember that dog food can become stale over time. 

Unopened dry pet foods must be used within 12-18 months from the sale date, and unopened canned food will remain fresh for two years after production. 

Nonetheless, once you open a bag of kibble or canned food, oxygen and moisture can enter, causing it to spoil much faster – with wet food only lasting up to several weeks following opening.

Therefore, it is essential to be aware of the indications that your food has gone rancid, such as alterations in the shade, odor, and consistency; a foul smell; or evidence of mold or bugs.

How to Store Dog Food Properly

So now that we know the different factors that can affect the shelf life of dog food, let’s talk about how to store it properly.

Proper storage is key to keeping your dog’s food fresh for as long as possible.

Here are a few tips to help you out:

  • Keep it airtight: Keep your pup’s dinner fresh by securely storing it in an airtight or plastic storage container. This way, you can prevent moisture and air from entering the food, which could otherwise lead to it going stale.
  • Keep it cool: Store your canine’s food in a cool (less than 80 F) and dry area; try not to keep it in hot attics or garages.
  • Keep it clean: To keep food from becoming contaminated, rinse and dry storage containers between uses. This will help prevent bacteria or other debris from lingering on the surface.
  • Keep it fresh: To ensure pet food’s freshness and safety, always store it in a clean container with an airtight lid.
  • Keep track: To keep track of essential information such as the UPC, lot number, brand, and manufacturer, store your dog food and treats in their original containers. Additionally, do not forget to check the “best by” date before feeding them to your furry friends!

So, these are some guidelines to help you keep your dog’s food fresh and safe. 

Remember, proper storage is key to preserving dog food for longer.

How to Tell if Dog Food has Gone Stale

Alright, so we’ve discussed the factors that can affect the shelf life of dog food and how to store it properly, but how do you know if your dog’s food has gone bad?

Here are some signs to look out for:

  • Rancid odor: If you detect an noticeable sour, putrid stench stemming from your storage area, chances are the food has gone bad.
  • Changes in color, smell, and texture: If the food has changed in color, texture, or scent, it is most likely not safe to give your beloved pet.
  • Mold or insects: Carefully inspect your food for signs of mold or insects. Discarding the entire bag – even if only a small portion is contaminated – is recommended, as it can cause health risks.
  • Processing or manufacturing date: Always check the expiration date on your pup’s food; an outdated product may have gone bad.
  • Proper storage: Consider the food’s storage. If an open bag has been left out for greater than 24 hours, or if it is in a manner that allows air and humidity to reach it, then its quality could have diminished as well.

It’s critical to remember that, aside from actively “going bad,” dog food can become nutritionally deficient with age. 

Thus, feeding your pooch outdated kibble is risky for their health and denies them the necessary nourishment.

Choosing the freshest dog food available should be a top priority: not only will it extend its shelf-life, but you can guarantee your four-legged friend is getting the best possible nutrition.

To keep your leftovers fresher for longer, secure them in an airtight container or lid immediately if not consumed immediately.

When it comes to your pet’s health, playing it safe is always the best option. 

If you ever feel concerned about the freshness of their food, discard what you have and invest in a new bag or can that will keep them healthy and happy!


Ultimately, dog food (both dry and canned dog food) can become stale if not stored correctly. Therefore, dog owners and parents must watch their furry family member’s meals to ensure their lifespan isn’t cut short by poor storage habits. Understanding the components affecting shelf life and appropriate handling techniques of your pup’s chow will ensure they get all the deliciousness they deserve!

It’s essential to consider that dog food can vary in shelf life, with dry food lasting longer than wet food and homemade having the shortest time. It is also crucial to be aware of other factors affecting the product’s lifespan, such as packaging, contents, and storage methods.

To provide the freshest and safest food for your pet, it’s essential to be mindful of signs that indicate spoilage. These include discolorations, changes in smell or texture, foul odors, and spotting mold or insects.
