Dog and horse, ox, sheep, pig, chicken are called "six animals". Some scientists think that dogs were domesticated by early humans from gray wolves, and the domestication time was from 40000 to 15000 years ago.

有科学家认为狗是由早期人类从灰狼驯化而来，驯养时间在4万年前~1.5万年前。被称为“人类最忠实的朋友”，是饲养率最高的宠物，其寿命大约在12~18年  。在中国文化中，狗属于十二生肖之一，在十二生肖中的第11位。

狗是由狼驯化而来的。早在狩猎采集时代，人们就已驯养狗为狩猎时的助手。因此，狗算是人类最早驯养的家畜。河北武安磁山、河南新郑裴李岗、浙江余姚河姆渡等遗址，都发现了狗骨骼，足证其驯养历史之久远。 

山东胶县三里河出土的狗形鬶，造型生动逼真，使我们得见新石器时代家犬的形态特征。陕西西安半坡遗址出土的狗骨，头骨较小，额骨突出，肉裂齿小，下颌骨水平边缘弯曲，与华北狼有很大区别，说明人类驯养狗的历史确实很早。

没有人确切知道人与狼第一次互动发生在什么时候。有科学家认为可能是在5万年之前，因为至少要花这么久的时间野狼才能发展出如今的基因差异。当时人与野狼分布在地球表面的许多地方，演化过程可能发生在好几个不同的地区。有些学者则认为狼在14000年前，甚至可能在16000年前的亚洲东南部，就已经被人类从野生狼驯化为家畜、即狗，用来玩、打猎、看家护院。
