Described as a "unique looking dog in a baggy suit," the Bloodhound is one of the oldest breeds of dogs that hunt by scent. Although affectionate, they can posses shy natures, sensitive to kindness or correction by their master. Colors of the Bloodhound include black and tan, liver and tan, and red, sometimes flecked with white. While Bloodhounds are extremely affectionate, they are take-charge dogs, so it is important to be kind, but be the undisputed boss in your household.
