Most dog owners are familiar with the moment they reach home and find their dog already waiting, sometimes at the door, sometimes near the window, or simply alert and ready as if they had been expecting that exact moment. It feels almost uncanny. How could a dog know you are about to arrive before you even step inside? This behavior is widely reported by pet owners, and researchers have studied it for decades. Surveys suggest that a significant number of dog owners notice this kind of anticipatory behavior regularly, where dogs appear to position themselves near entry points shortly before their humans return. The key question is not whether it happens, but how it happens.
