Like all poop origin stories, this one starts at the other end, after sperm whales snarf down an afternoon snack of squid.

像所有粪便起源的故事一样，这个故事从另一端开始，在抹香鲸狼吞虎咽地吃下下午的鱿鱼零食之后。

And while some dogs will snarf down most poops they come across, lots of dogs will actually use their keen noses to sniff out fresh poop that has specific vitamins or enzymes they’re craving.

虽然有些狗会咬掉它们遇到的大多数便便，但实际上很多狗会用它们敏锐的鼻子嗅出新鲜的便便，这些便便含有它们渴望的特定维生素或酶。
