If I'm not mistaken these units are those that use Bloodhounds to track poachers in Virunga
AFAIK at least at the beginning they were trained by Dr. Marlene Zähner, a Swiss vet who brought Mantrailing to Switzerland.
Seeing working BHs at work is like seeing magic. They don't need eyes, they see with the nose
Handlers must be fit. These big dogs don't keep sniffing around for long, if they get the scent they just GO.
I've seen a trained dog successfully following a 24h old 2km trail left by a person that had been transported in a closed car.
My respect to everybody there
