if you want a beagle to run fox with you sure don't want one that "loves to run deer". one that runs rabbits and also runs fox would be much easier to work with. you could put up with a rabbit chase now and then alot more than a deer chase esp. if you are running on snow and putting him on fox from the start. or once you got him running fox you could break him off rabbits. most guys that run fox start their pups on rabbits. it teaches them to handle a track and once they get running fox they usaully leave the bunnies alone.
