Although all dogs have a better sense of smell than we do, some are just better at it than others. Dogs have over 200 million scenting receptors, while we mere humans only have about five million. But then again, it takes more than just a super sniffer to be a good tracking breed. Some dogs have built-in scenting accessories like long floppy ears that scoop the scent from the ground, and wrinkly folds of skin that hangs down to hold the scent particles while they are tracking. It also helps in some cases to have short legs, so their nose is closer to the ground where the scent is. excellent breeds for tracking should be good listeners, strong-bodied, and obedient, while also having a lot of energy and stamina. Here are the top 11 dog breeds for tracking.
