Czar has no formal bloodhound training, only flushing and retriever work on small game (his first real season). However, I have lots of Roedeer on my lease and he developed a passion for them, tracking their spoors into the bushes until he flushes them. He then starts a chase but, fortunately, he'll stop at a single whistle blast. This was his first real tracking and it was not premeditated, I got him out of the car as an afterthought for fear of losing the deer in the falling night.
