How long do opened dog treats stay fresh in an airtight container?

Hello. Dog kibble has organic compounds like fats, just like any other perishable food might have. Generally, if a kibble is not used within a month , it is a good idea to put the remainder in the fridge or freezer to prevent the breakdown & loss of essential vitamins & nutrients & rancidity of the fatty acids. As long as the original package seal is not broken, a food might remain relatively fresh for months, but once opened, it is good to try & use the entire contents within 4-6 weeks.

The dog food may be "fresh" and palatable, but it will have lost some aroma and definitely a lot of the vitamins. Usually Vitamins stay actively working for about 6 months, so if you have a bag that has been opened for longer than 6 months the quality of the food is less than when it was originally opened. You can feed the food, but realize, that its nutritional value may be lower than when the bag was opened. If the manufacturer tells you that after 18 months the food was as good as when it originally was opened, you want to see the respective research proving that. In my professional opinion: the faster you use up the food after opening, the better.

The glass jar may not seal as well as the original packaging in this case. I doubt that it would cause Chloe any harm to feed her these treats, as they are likely just stale. However, I agree that a general rule of thumb is that treats are best fed when they are fresh and able to be broken.

Great question! I always keep my dog food in an airtight plastic container. It helps keep it fresh, and the container also prevents any other creatures from getting the food such as insects. I recommend a container. I hope this helps :-)

The recommendation of how long a food lasts is usually arbitrary and often not based on any studies, so it's difficult to say how accurate this information is. Of course, storing food for a long time can lead to infestations and growth of harmful microorganisms, but this depends on how the food is stored and the climate you live in.

Dry commercial dog foods are shelf stable and do not require refrigeration or freezing for storage. Store any open food in a food-grade container that seals well at room temperature. Be sure to use all food before the expiration date printed on the bag.

I would recommend contacting the manufacturer of the treat. They will have first-hand knowledge of what is in the treats and how stable it is under those conditions. If you are not sure if the treats are safe then I would not feed them to your dog.
