长期以来有这样一种说法，即一些狗往往和主人有着相似的相貌，不过也有很多人把这种说法当成是一种纯属玩笑性质的调侃。但是，最近，一些心理学家经过调查研究后发现，这种说法并非无稽之谈，而是有一定的事实根据的。美国的社会心理学家就对这种说法郑重其事，并做了饶有兴 For a long time there has been a saying that some dogs tend to have similar appearances with their owners, but many people regard this argument as a joke-type joke.

American social psychologists are serious about this statement and have done a good job.
