CBS News reports from Pittsburgh:
“The dogs are bred to move livestock. In this case, the fearless canines are trained to handle massive elephants. They charge and nip at the elephants’ feet and trunks. The elephants have such respect for the dogs that even if they hear a handler say the name Major or Zeta, they take notice.
“They are very alert when they hear the jingling of the dogs’ licenses as they come running around the corner.”
