I can't remember when I didn't have a dog, but I remember my first hunting dog. Roscoe was a large black-and-tan, bugle-voiced coonhound. Many a night that dog and I would head to the woods. I was armed with a 22-caliber single shot rifle and a kerosene lantern. Roscoe and I walked the countryside waiting for him to catch the scent of a raccoon. What a thrill when he picked up the trail. What a remarkable nose! All through history man has used dogs as companions and hunting partners. Many canine varieties have been bred specifically for hunting. One stands out from them all—the bloodhound, which is very similar to coonhounds and often bred with them.
Originally developed to hunt wild boar and deer, the bloodhound can pick up a scent up to twelve days old. Often called a nose with a dog attached, the bloodhound has a larger nasal chamber than most dogs. It is believed that bloodhounds can detect as few as one or two invisible scent particles when on a trail.
