Your dog may not understand the importance of keeping his or her food fresh using dog food containers, but that's what they have you for! If you are using an old pet food bin or just the bag or box the kibble came in then there are a number of problems you could run into. Bugs can easily crawl inside a partially open bag or a container with a loose lid on it. Your dog is also pretty smart and has probably learned a trick or two about how to open that old bin you've been using for the last several years. Luckily there are lots of alternatives out there so go ahead and throw that old unit out… it's time to upgrade to a new dog food container!
