Whenever Cyclone Hobbies manager Kyle Belman fires up a mini-drone, Harley, the shop’s friendly Yorkshire Terrier, immediately jumps to her feet. As soon as the drone is airborne, Harley gives chase, excitedly scampering after the radio-controlled (RC) vehicle as he deftly maneuvers it around the shop. “Harley gets a lot more exercise chasing drones than she ever gets running after a ball,” says Belman.
