Video captures two sides of this dog
Kirk the Border Collie is unable to contain herself as she watches her own winning run from the 2017 Small Dog Agility competition at the 2017 Incredible Dog Challenge Western Regionals with her handler, Channan Fosty. While fixated on the video for the 32 seconds of her run, Kirk jumps up and down over 3 dozen times—more than once a second. Her enthusiasm is contagious and with each jump, I found her more endearing.
