Here at the AKC, we never get tired of learning more about dogs, whether it’s a new study on canine behavior, a statistic from our database, or even just cool facts about a dog’s impressive physical and mental abilities. You may know some of these already, and others may be more of a “wait, really?” situation, but we think you’ll find all of them entertaining. Check out these 30 fun dog facts.
