Turns out dogs sniff each other's butts because it's all about chemical communication. No, really! Just by sniffing they can learn how their doggy friend is doing that day by sensing their diet, gender, and emotional state! If only humans could do that with just one sniff! Just kidding! 

That's not all chemical communication is about though. Watch the video in its entirety to get the butt sniffing scoop!

So what did you think of this incredible and revealing video? Even though it's hard to completely understand all of the scientific jargon, what we can gather is that our dogs are pretty intelligent, to say the least!

Turns out our dogs aren't obsessed with other dog butts…they're just getting to know their friends in a special aromatic way! Who would have thought!
