Hound isn't one breed but a label for scent hound and sighthound types, and on adoption listings it usually means a mix with Beagle, Coonhound, Foxhound or Plott ancestry. Expect a short coat, long ears, a medium build somewhere between about 20 and 70 pounds, and a voice that carries.
What a hound looks like matters less than how it was built to work: following a trail for hours, alongside other dogs. That makes many hounds social and mellow at home, but also stubborn, food-motivated and quick to wander. In Wilmington, where yards often back onto neighbors and walks pass plenty of interesting smells, a sturdy leash, a secure fence and some patience with training go a long way.
