Usually they do, especially if it's going to a kid. Maybe they hope the kid will get into hunting it eventually, I don't know. They don't think much of dogs that are "just" pets and don't hunt. I can't get too mad at them though, because these are truly wonderful dogs, and have about the most stable pemperaments I've seen in any dogs, so they must be doing something right somewhere.
Neither I nor Sparks got our coonhounds from breeders though, they are both rescues. There always seem to be purebred coonhounds available in rescues, they are prone to getting lost when hunting. Something you should consider. These are both beautiful dogs. Try petfinder too.
You need to look up "coonhound", "hound", "foxhound", and even "beagle" on petfinder. Shelters don't always know what they have.
