How Long does Dry Dog Food Last?

This is indeed a good question, and I’m sure you are aware that a bag of dry dog food bears the expiry date. But then have you thought about how long it will last when it is opened. You will agree with me that the best date on the bag is only applicable when it is not opened.

Of course, it is true that a bag of dry dog food can last for many months between 6months -1year 0r even years. However, the best date of dry dog food is estimated based on when the bag of the food is yet to be opened.

Now, do you know what happens when you open the dry dog food bag? If you don’t, well, now you know that the moment the bag is open, oxidation process begins. The quality of the food automatically begins to depreciate and believe it or not, the expiry date on the package will become rather meaningless.

Oxidation makes the food nutrients to start depreciating and it also weakens vitamin potency. When this happens, the dog food becomes rusty with time but not long enough as expected. When this dog food gets rusty, the nutrients also begins to depreciate.

Since dog food mostly contains average fats, upon rusting these fats start smelling or tasting bad because it has stayed for too long. This can lead to the presence of bacteria which could introduce the toxic substance into your dog’s body. You know very well that it could make him feel unwell if he was to be served that food. This smell might not be obvious since you are dealing with dry supplement.

 Speaking on how long dry dog food can last, Steve Brown a leader in dog nutritional diets, posited that an open bag of dry dog food can last for a week. On the other hand, a vet and also a pet nutritionist, Dr. Frick A proposed a maximum of 3 weeks so after this period and you still have a remnant of food, you dispose of it for your dog’s health.


Always buy smaller bags depending on how much food your dog (s) consumes. So choose a good size that can take care of your dogs for short a period of time. Feeding your dog (s) with fresh food will do more good than harm. Don’t forget that your dog is your best friend.
