I asssume that he told you this, and that you're not saying you
actually saw it happen. d8-)

"Barking" squirrels is an old legend. It can be done -- with a
high-powered rifle, but not with a .22 or an air gun.

A squirrel hunter I know tried barking them for a while, but decided to
just shoot them in the head, it was easier. He was good enough to get 4
squirrels with 5 rounds. He would go home with dinner when he had 4.
