That is why Sequoia's kennel has the kennel latch, a bungy cord and a chain with a padlock on it while she is inside...it is on pavement with chainlink on the top also so she can't climb the walls. When in the house the doors are locked and when she is on the zip line outside she is hooked up on the line itself with another safety attachment also on her collar so if one gets unhooked there is a second one still hooked up. She already took out the neighbor's rooster when she accidently got away from us......
