I have a red bone hound, he found a deer for me the other day and I’ve never trained him. He does chase deer on his own all the time Not sure if wasn’t just a fluke, we will see if I kill another that doesn’t drop immediately
Yes many dogs are totally capable of that. Its a bit different with a trained dog that knows exactly what they are doing and will detect and track aged tracks for long distances. If you want to know more I would check out john jeanenney. He's dead now but he has blog called born to track and good book on the topic. You may be able to find some podcasts or interviews with him.
