They're great animals. Funny personalities.
Ours has a feral aspect to him. When he was a puppy, I think he would have attacked and eaten our infant granddaughter. He growled whenever he saw children. We totally had to dominate him which we had never done with a dog. He then learned that children throw frisbies and once he made that connection, we never worried again. But once, when he was about seven months old, I took him with me in the support vehicle when my husband did Ride the Rockies, a bycicle ride. We were camping in close quarters one night when he startled, chased down a bunch of children and, being a heeler, nipped at the heals of the little girl in back. He knew as soon as he had done it that he was in trouble and slunk back to me. I chewed him out and told him to go abologize. He slunk over to the girl's mother and licked her foot. I am not making this up.
