My dog passed away many years ago now, but “Oops” is one that I hear really commonly because I would drop stuff off the counter when cooking. Just saying “Oops” would have the dog come running to see what good stuff hit the floor.
Also, not exactly a command, but that dog’s hearing was so exceptional that he could hear the jangling sound of me picking up his leash while I was inside the house and he’d come running from the back yard across the whole house.
Of course, his hearing was always selective. The things he loved to do he could hear perfectly, while things he dislikes such as obedience training it was like he was deaf lol.
