In this episode, the discussion is about teaching your dog to think before acting when in the fevered activity of hunting: their favorite thing on the planet.  You can develop awareness and thoughtfulness in a dog, before going through fences, into heavy cover, over ditches, launching into water, etc.  If you can take the time to teach them how to keep from hurting themselves, you will never regret it.  Lots of crazy things can happen while hunting.  Best enjoyed if you both are very prepared, literally and mentally...
