You smile as your adorable little puppy returns to you with its favorite ball in his mouth. Your four-legged friend drops the ball at your feet and then looks up at your with those big puppy eyes. How can you resist? You pick up the ball and launch it high in the air. Just before the ball begins to arc back down toward the ground, your puppy spreads its wings and soars up to catch the ball in its mouth. Gracefully, your companion sails back to you, gliding through the air with wings outstretched and blue fur rustling in the wind. What a good dog.
