Check out Guy's feet in this photo....all four feet off the ground at a TROT!

Can't decide if he was switching from a gallop to a trot and that's why all four are off the ground or if he's showing GSDs how it's done! LOL! ( In case you aren't a student of dog movement - when a dog trots normally there are two feet striking the ground and two feet in the air.)
