Anyone who has been around dogs knows they pay attention to what we’re doing, but you may not realize just how closely they’re watching you. Â Sarah Marshall-Pescini, a scientist in Italy, has shown that dogs pay attention to how we treat other people—in particular, how generous we are other with other humans. This observational ability is pretty rare. Â Humans, chimpanzees, and some large fish are known to do it, but a big difference is the chimps are watching how a chimp cooperates with other chimps and the large fish watch how “cleaner fish” cooperate with other large fish. Â Dogs, on the other hand, are watching how humans deal with other humans, not just how humans deal with other dogs. Â Pretty cool!
