Cool show! I'm reguards to season 2 episode 6... Vizlas are pointers. They've been bread to do that over many generations. I've seen pointers point, hearding dogs heard, and retrievers retrieve. All without training. But training greatly hones the bread in trait. I have a friend who's a herpetologist who had a vizla. And since the dog was raised around reptiles, whenever he would go out looking for reptiles in the wild, the dog would point them out for him. Even though he never trained the dog. Not a phenomenon. Very natural behavior for that breed.
