Taking flight for the First Time!

Nope, Not birds. My pup. I decided to take him to the public docks, to see what he would do with a runway and launch pad. First attempt ended with him slamming on the brakes and barking at the bumper.
By the 5th time, he was hitting the dock full speed and going airborne. His muscular, large build isn't stopping him from getting some serious distance off a dock that is only a 2 feet out of the water. He looks like a linebacker, flying over the line to get the QB. Geese in a field or crips don't stand a chance.
