Dry dog food does expire. Unopened, a bag of dry dog food can last up to two years, says Chavez. Once the bag is opened, it is only good for a few weeks. “Kibble is ultra-processed pet food and contains preservatives designed to give it a longer shelf life,” Chavez says.
How long does dry kibble last?
An average dry kibble product will have a shelf life of about a year. But once you open the bag, you only have approximately 2 weeks to finish it before the oils in the kibble food turn rancid. Oils become rancid by being exposed to oxygen and becoming 'oxidized'.
