Hey dont laugh, my pit bull does the pointer thing too, its hilarious but its only with birds for some reason, nothing else.
I know your laughing right now but its true. My dad has always used hunting dogs, he thought I was pullin his chain till he saw her do it.
Anyhoo I just love GSP's, a guy down the street just adopted a 9 month old from a rescue group, he calls him Hank and Hank has proved to be a very smart escape artist.
