The Bloodhound is a large scent hound originally bred for the purpose of tracking and trailing human beings.This makes the dog an excellent aid and an important part of a search and rescue team. With its tail held high and a free, elastic gait, the Bloodhound is noted for its endurance more than its swiftness. Its short and dense coat offers protection from thorny brambles and gives the Bloodhound a dignified and noble appearance. The acceptable colors for the Bloodhound include black and tan, liver and tan, or red. The Bloodhound is not usually harmful toward humans, remaining calm at home. And while it makes for a great family pet, the Bloodhound may be shy around strangers. It can be difficult to train a Bloodhound at first because of its playfulness, stubbornness, toughness and independence. These characteristics, however, are what make the Bloodhound a tireless trailer and a loyal companion.
