Doe Killer, as posted Huntnma says, bloodhounds need more of EVERYTHING! Food, water, space, love, attention, energy, ruined clothes, ruined yard......
However, they are very loyal and loving and are good with older kids. Too big and energetic for small kids though (unless your kid is a lot tougher than mine). They are very large dogs if you haven't seen any in person, a big male can go over 100 pounds easy. They can look intimidating, but they are more likely to drown you in slobber than bite you. And they really do slobber a lot.
Whatever you do, I would recommend you go and visit a breeder or at least a current owner to get a feel for them before you commit to a puppy. Best of luck.
