They have got out two times since the new hot wire fence went up, once the West Texas breeze blew the Igloo dog house on to the wire shorting it out. The next time the neighbors were playing on the trampoline in their front yard. The big dog took the hit to bust lose. He swats at the wire with his paw, until he breaks it or jerks it from the insulators. He gets hit but he just don't mind.
TASER!
