How Do You Know if Canned Dog Food Is Bad?

Canned dog food is a convenient way to feed your pup, but it’s important to know how to tell if canned dog food is bad. Canned food can easily spoil, and feeding your pup something off can cause serious health issues. To ensure that you’re only feeding your pup the best, here are some signs to watch out for when it comes to canned dog food.

First and foremost, check the expiration date.

All food has an expiration date for a reason, and it’s important to stick to it when dealing with canned dog food. If the date has passed or is close to passing, you should replace the can right away. The same goes for cans that are dented or bulging—these could be signs of spoiled or contaminated food inside.

Another thing to look out for is a rancid smell. This usually indicates that the food has gone bad.

Don’t be tempted by its color or texture—if it smells odd, it’s time to discard it. Additionally, if there are any signs of mold growing on the outside of the can or on the contents inside, then you should get rid of the product.

Taste testing is not recommended when trying to determine whether canned dog food has gone bad; it may seem like a good idea at first, but this could lead to potential health risks if you’re not careful. Your pup won’t be able to tell you if something tastes off either.


The best way to know if canned dog food is bad is by checking its expiration date and making sure there are no signs of bulging or denting on the can. Additionally, pay attention for any rancid odors coming from the can as this could indicate that the product has gone bad. Lastly, taste testing should be avoided as this could lead to potential health risks.
