SaR training with victim hidden high

Another weekend with SaR training in the mountains around Athens.
The first video shows our exercise about teaching the dog that the target scent can be on an altitude, and of course it starts by putting the victim a few inches higher and gradually increasing the altitude to the point we see in this video.
The second video shows our exercise in testing the behavior of a dog when it doesn't have any optical stimuli.
We see that the dog trusts its nose and indicates the closest spot where it finds the air scent of a human.
