In this episode of The Watering Hole, Todd and Justin welcome back the infamous Tracker John to share the wealth of knowledge he has gathered from years of following thousands of blood trails. The discussion dives into the fascinating science of how tracking dogs process scent, specifically how they can distinguish between different types of blood—such as lung, liver, or gut—and how their behavior on the trail can help a tracker predict the likelihood of a successful recovery. John provides a professional perspective on the mechanics of deer recovery, explaining how environmental factors like moisture in the snow can impact a dog's ability to stay on a trail and why achieving two exit holes is a major advantage for arrow penetration and tracking.
