Dogs have a pretty decent memory. They can remember who's nice and who's mean, what to do when their mom says "sit," and (usually) that they aren't supposed to jump onto the couch. But they have a very tangible motivation to remember each of these things—whether or not they earn a treat or get a punishment depends on it.
But then there's what's called "episodic" memory. That's memory of things that you don't realize at the time are significant. A new study indicates that dogs do actually remember events that don't seem important at the time—and the way researchers made that discovery is fascinating.
