Have never seen a hunting dog that can actually catch a rabbit. Have seen where a group of beagles managed to catch one but that was just luck and nothing trained for. As OT said most hunting dogs will trail the rabbit and never actually get close enough. From my experience here when beagles get on a cotton tail the cotton tail will usually run a square type pattern to get back to its safety. A marsh rabbit will go all over looking like an etch a sketch pad. None of the dogs get close enough to either one.
