As with all tricks, make sure to have some sort of food motivation for your dog while he's in training. Ending3: [substeps] To learn to spin your dog, run around your dog, yelling, " good dog! " as he spins over to you and picks you up. Have him bend his front paws in the opposite direction you just threw him.
