Here we will do a deep dive into a few ways to check if dry dog food and canned dog food have gone bad.

The Date of Expiry

Perhaps the most obvious action to tell if dog food has gone bad is to look at its shelf life, indicated by the expiration date. Similar to the food we consume, the expiration date is a guideline as to when the food loses its freshness. Some may argue that a day or two past the expiration date is acceptable, but we would only condone that if you are finishing off a pack of food.

For people buying a fresh new bag of pet food, make sure you give yourself and your dog ample time before it’s past its expiration date. For dog food, there is also a best by date, which ensures the health and safety of your dog if the food is consumed within the labeled best before or best by date. Usually, you can expect a shelf life of a year to a year and a half.

It’s crucial to also keep in mind that the expiration date and best by dates is for unopened dog food bags. Once it has been opened, it’s best to consume the food in a timely manner within the month.

The reason pet food manufacturers have a best by date for pet foods is due to oxidation. Once the original bag or canned food has been opened, air and moisture will start to seep in and degrade the food. Over time, the degradation will lead to food spoilage.

There may be a chance you purchase an original bag of food that has spoiled even though it hasn’t been opened and isn’t past its expiration date. There is also a chance the kibble has been opened for too long and started to spoil. In both cases, there are certain features to be aware of when inspecting your dog’s food.

+ Check the Odor

More than likely there will be a rancid smell to the canned dog food or dry dog food if it is past its shelf life. The smell should be pretty noticeable, but if it’s faint to you, your dog should be able to detect it. So if your pooch is avoiding his food and you notice the aroma is slightly off, then chances are it is bad.

+ Check the Appearance

Sometimes the spoilage is easily detected by the eye. If you notice any mold or even bugs of some sort, then it is a definite sign the food went bad

If you haven’t noticed anything detectable by these two senses but your dog is avoiding the food or has started to feel ill, then you should inspect it more closely. The food you feed your dog could be the catalyst to physical symptoms.

If you live in a place where heat and humidity are an issue, then a dog’s food without proper storage will impact the shelf life and freshness.

The preservation of either dry dog food or canned dog food is the same – it all hinges on the storage container. Pet foods usually come in a bag, but once it’s opened, then the contents are compromised. There are dog food bags that come with a Ziploc seal, and this will suffice in places with dry air and moisture control since a dog food bag is optimized for this. However, in an environment where it’s hot and moist, food storage methods are more important than ever. You can’t just rely on a sealed bag.

In areas such as these, food in the bag should be transferred to a storage container. If we’re talking about wet dog food, then we would also suggest your dog’s food be transferred to a properly sealed container when opened or stored in a cool dry place if not. Opened cans or ones stored in a container should be refrigerated. An airtight dry food bin will help make sure your dog’s food stays fresh for longer.

Subscription fresh dog food has their own method of storage, which should be communicated to you on their website. More often than not, the frozen bag of dog food should be put in the freezer and thawed before use. We do not suggest refreezing the food if possible to prevent it from going bad, so make sure you measure out the portions exactly.

What about Treats?

Dog treats are created in a different way than dog foods, but the short answer is yes, they can still go bad. The shelf life of dog treats depends on the ingredients and if there are preservatives. Of course, we hope that the treats you feed or dog are as natural and organic as possible.

Much like dog food, their treats should also come with a date of expiry and an estimated shelf life with a best before date. Keep in mind that the more natural the treats are, the quicker they should be consumed after you open the bag. For dog treats, they usually come in a resealable food bag, so all you need to do is store them in a cool dry place.

If you make your own dog treats, such as cookies, you can store them accordingly to how you would human treats.

The same logic applies when trying to determine if dog treats have spoiled, and that is by looking out for a rancid odor, discoloration, mold, and careful monitoring of expiration dates.

What Happens if My Dog Eats Bad Dog Food?

Let’s say your dog happens to eat bad dog food, what can happen? We’re sure that question is plaguing the minds of many pet parents because the symptoms are similar to a dog eating almost anything else they shouldn’t eat.

The most obvious sign of your dog eating something he isn’t supposed to be food poisoning. This can come from bad food and spoiled treats, but other causes range from eating feces, picking up dead animals on walks, and eating something their system cannot handle.

How can you be sure it’s food poisoning? The signs are quite obvious and they manifest in vomiting, a lack of appetite, lethargy, diarrhea, and more. In more severe cases, your dog can exhibit even more frightening symptoms such as seizures and tremors. Of course, these are reserved for the more serious cases but the most common symptoms are lethargy, vomiting, and an upset stomach.

If your beloved dog has eaten bad food and is showing the above signs we mentioned, let him get it out. Sometimes once your dog gets the spoiled dry dog food or wet food out of his system, he should slowly regain some normalcy. One thing to make sure to do during the expulsion period is to keep water accessible. Vomiting and an upset stomach lead to dehydration in your dog.

As a rule of thumb, give your dog one day or 24 hours to recover. He may not be 100% after the first day, but he should display signs of recuperation If not, then it’s time to take a trip to the vet. If he seems to get better only to have his condition worsen again over the next few days, then also call your vet.

As a dog parent, your concerns are always valid when it comes to the well-being of your dog. It never hurts to schedule an appointment regardless of how serious the food poisoning is.
