Snarled at them. Wouldn't go near them. But if I brought home a date I liked, Harper, a Shar Pei/Labrador mix, would curl up right next to the woman and turn on the charm. It took me several years to figure out that my dog wasn't a good judge of character; she was just good at reading me. She liked the people I liked and disliked the people who rubbed me the wrong way. For dogs descended from lines bred for protection and companionship, this talent makes sense. A dog adept at distinguishing friend from foe was likely to be kept around and bred, and one very good way to tell friend from foe is to read your master's body language.
My confusion about what was going on in Harper's head reflects a common misconception that is also apparent in the ways dogs are used in criminal investigations. When we think dogs are using their well-honed noses to sniff out drugs or criminal suspects, they may actually be displaying a more recently evolved trait: an urgent desire to please their masters, coupled with the ability to read their cues."
