狗大多数时候是善良的、友好的,喜欢人甚于喜欢同类。这不仅是由于人能照顾它,给它吃住,更主要原因是狗与人为伴,建立了感情,对自己的主人有强烈的保护心。有的狗从水中、失火的房子里或肇事的车子下救人,有的狗还会帮助受难或受伤的狗友同伴解除痛苦。狗一般在兴奋或见到主人高兴时,就会摇头摆尾,尾巴不仅左右摇摆,还会不断旋转。尾巴翘起,表示喜悦;尾巴下垂,意味危险;尾巴不动,显示不安;尾巴夹起,说明害怕;迅速水平地摇动尾巴,象征着友好。狗尾巴的动作,还与主人的音调有关。如果主 Dogs are kind and friendly most of the time, like people more than they like.
