Three Hearts Border Patrol - Gunner is a great guy that has never met a stranger.  GUNNER IS A RETRIEVING MACHINE!!  Show him a ball and the next few hours are filled with playing.  He has been very playful with older kids and adults, yet very slow and easy with small children and older people. Gunner went through the training to become a narcotics dog, however during the final exam, he flinched when a man jumped out from behind some boxes.  That was an automatic dismissal from the program.  Gunner then moved into our program. He loves to be with people and bonded with us immediately.
