From the American Kennel Club (AKC):

You work hard to teach your dog good manners. There’s one area, though, where you probably won’t have much success: Asking them to “stop being so nosey!” It won’t work because your dog’s keen sense of smell – which is 100,000 times stronger than humans – makes him naturally “nosey,” and thus innately ideal for the sport of Tracking. In the world of working dogs, these skills are put to incredible use for emergency search-and-rescue.

So what do you do with your ever-nosey dog? Get them involved in an AKC Tracking event where they can sniff and smell to their heart’s content, and demonstrate that natural ability to recognize and follow a scent. It’s the perfect way for you and your dog—whether purebred or mixed breed—to enjoy many hours together, outside in the fresh air, honing those natural abilities. Champion trackers can compete in the AKC National Tracking Invitational.
