@sanjibasenji I guess because I come from a farming community which also hunts, I have known the term since forever and yes, my Chezz and her daughter Trouble worked in tandem, nose to the ground, in patterns, mostly kind of oblongs. They taught themselves to quarter the ground when hunting and I recognised it as soon as it happened - many times over their long lives.
That is a very interesting article and much of it pertains to training any dog, not just a hunter.
