It kind of reminds me of a time I saw a chihuahua pick a fight with a rottweiler. The little guy kept nipping at the rottweiler who, at first, ignored it. After a little while though the rottweiler had had enough and picked the chihuahua up in his mouth and shook him for a few seconds. That pretty much ended the chihuahua's aspirations of being king on the hill. As my daddy said, "Never pick a fight you can't win."
