If you would like a close second to a beagle for hunting rabbits try a basset hound. However, be careful that you get one with a good pedigree of rabbit hunting. If your dad is worried about the constant baying of a beagle. I currently have six beagles that I use strictly for rabbit hunting and AKC field trials. All of them are quite in the kennel. My secret use a Tri-tronics bark limiter when they are just a pup and they learn real quick not to bay in the kennel.
