The bloodhound is the only breed of dog whose evidence is admissible in US courts. The hound, originally bred as a hunting dog, has been used in judicial systems dating back to Roman times. A single bloodhound has 230 million olfactory receptors lining its nose; while the German shepherd has only 225 million olfactory receptors and humans have five million. Due to their ability to pick up scents, bloodhounds have been known to stalk individuals for several hours to several days.
