Besides all these, there are also police dogs who aid the police in their duties and military police dogs used by the armed services. These two kinds of working dogs have jobs of a more dangerous nature, even to the point of giving their lives for duty's sake.
此外，還有協助警方出任務的警犬、軍隊使用的軍犬，這兩種工作犬的工作較具危險性，不乏「因公殉職」的例子。
