These two were quite the challenge. The one Zachary was running with loved the walk, and was fine walking with us, but if you got to close to his face or body with your hands he'd start to growl & bar his teeth. He had come from a very abusive environment, leaving him with little trust for new people, but he liked us enough to be walked by us! The one I was walking had been ran over. His back and back legs had been broken. He has healed & recovered remarkably, but he still has trouble walking long distances. He'd happily be walking, when his back legs would sort of collapse. Poor thing was so resilient and not at all bothered by his constant collapsing, though.Being in Thailand, we had beautiful scenery all around us to enjoy.
