no.....not all dogs can track deer.......some its easier than others but you still have to train them to follow the injured deer.! Its not all about the blood either...what happens when they run out of blood? They have to be taught to track the smell of the wounded deer not the blood from that deer but his oder he omits from his feet. every deer has their own smell so the dog has to put the smell of that deer and blood together and when the blood runs out....its the odor he goes by!
