What’s more expensive … your dog’s kibble or the bag it comes in?

Pet food companies invest heavily in packaging. Packaging with compelling pictures and benefits helps make sales. And packaging is also critical to the safety of the kibble. Experts with PhDs develop and test your dog’s kibble packaging so it can sit on the shelf for months or years and still hold much of its nutrition. And if they get it wrong, dogs get sick.

But their job ends when you open up that bag of kibble. As soon as you open it, the food changes quickly. And those changes can be toxic to your dog.

So how long does that bag of kibble really last?
