Whatever corner of the globe you find homo sapiens in today, you're likely to find another species nearby: Canis lupus familiaris.

今天无论你在世界的哪个角落发现了人类，都可能在附近找到另一个物种：熟悉的狼疮犬。

We keep all dogs in the same species, Canis Lupus familiaris, because we know that they can breed with one another and make more puppies.

我们让所有的狗都属于同一个物种，Canis Lupus familiaris，因为我们知道它们可以相互繁殖并生出更多的小狗。
