I wonder if there is a similar substance in dogs. Before I had a dog, I had little interest in these creatures. Now, I notice dogs constantly. This morning I heard a brief discussion about the death of Target, a former stray who, along with several other dogs, thwarted a suicide bomber in Afghanistan. Target was accidentally euthanized. Honestly, I got a little choked up as I heard the story recounted.
Target and the other dogs who were with him in Afghanistan demonstrated the quality of altruism - unselfish concern for others' welfare. How remarkable that such a lofty emotion can be demonstrated by a simple dog. How pathetic that the dogs were morally superior than most humans.
Has my little dog affected some chemical change in my brain that makes me partial to other dogs? Or have I been moved by a truly remarkable story involving purity of spirit? In any event, there is a lesson here for all of us humans, dog and cat lovers alike. Would that we all could demonstrate gratitude for the simple things that others do for us. Would that we could all be sufficiently brave to protect and defend our pack.
