A common misconception is that bloodhounds run in packs tracking down the scent. Sometimes this may be the case in places like England but in North America bloodhounds are used as solitary trackers. When Bloodhounds are on a trail they usually are silent and do not bark or howl as other scenthounds. The original use of the bloodhound as a leash-hound is to find the scent but not disturb animals or let prisoners know that the Bloodhound is on their trail. This requires silent trailing.
Bloodhounds can weigh anywhere from 33 to 50 kg (80 to 110 lb), although some individuals can weigh as much as 72 kg (160 lb). They stand 58 to 69 cm (23 to 32 inches) high at the withers.
I think owning a Bloodhound would be a good idea, it would be great to have a Bloodhound around in case a loved one turned out to be missing!
