Pogo has just 2 speeds, “on” and “off”.  Put her feet on the ground and she is off instantly jumping, spinning, running, and launching at full speed.  But pick her up and hold her on her back then she instantly melts in your arms as if tranquilized.  Pogo learned flyball in record time and loves to spring off the box.  She continues to improve in speed with her current personal best being 4.489 seconds.
