I recently got a new beagle pup. she is 4 months old and I am looking to train her to trail deer. I haven't had her that long and she if full of pup. At what age do you start with beagles runnng deer. I have tried some of a deer liver to get her excited but she wouldn't have anything to do with it. Ditto on getting her excited on the deer leg I saved. I am kinda stumped. How do you get a dog on deer?
