And then they use this great power of smell to detect the nuances of the subtle differences in each others’ poop.

No two dog butts smell the same.

I remember when I was a kid asking my mother why dogs smelled each others behinds (butt was a dirty word back then). She went into some long story about back in the olden days the dogs took their butts off when they entered a house like you would take your hat off and hang them all on a hook. One of the dogs looked out the window and yelled, “CAT!” and all the dogs grabbed a butt and ran out the door. They were just trying to find their own butt. My mother had quite an imagination, apparently.
