Hi, I am Marcus de la Houssaye,
owner and operator of de la Houssaye'e Swamp Tours
near Lafayette, Louisiana.
I bred and train Louisiana Catahoula Curs for blood tracking dogs.
Do I do what you see in this Youtube video below? NO!
But I like to keep it simple: Bring a hungry dog who has been fed and raised eating raw meat, to a kill site, and walk them down a blood trail to a dead deer or gut pile and let them eat.
Repeat as often as possible. But that is just me, you can complicate this "training" stuff as much as you like.
Furthermore: this guy in the video makes some very important points that I agree with completely. Such as: A wounded deer gives off a completely different scent than a hot unwounded deer.
And given time, experienced blood tracking dogs learn the difference.
I like the video, but even though I keep deer legs frozen year round, I doubt this is needed as much as putting dogs on wounded or dead deer blood trails during deer hunting season.
But that is me. I am not the man in the video below, I am just sharing for your learning experience.
I am sure you will find this video interesting.
