Ziggy loves football. He tried out every position and every play he's ever seen on TV. First, he practiced hiking the ball, while giving the opposing team his best tough dog glare.
Then he tried out being a receiver, catching long passes thrown just over his shoulder.
He worked on his running game for awhile.
He practiced his best feints to avoid the defense.
And when the other team got the ball, he got a chance to practice his fumble recovery skills.
All in all, Ziggy is quite the football player. Which may explain why he has so much fun running at people or other dogs full-speed and knocking them down. I thought it was too much puppy exuberance. It turns out it's just another chance for Ziggy to practice his football skills. I think he'd make an excellent left tackle.
