A buddy of mine has 4 beagles and we're training them to run rabbits. I've done a lot of research on the subject and told him that he should have started earlier w/ more training, but that's beside the point. They are just over a year old, but when they hit a deer trail, they bark and take off after the deer. What's the best way to get them off deer and onto rabbits? We've got shock collars and have started shocking them when they hit the deer trail and rewarding them when they bark on a rabbit trail. Is this good? Any suggestions are more than welcome.
