If they don’t understand what vision is or really believe it exists... what do they think the dogs and horses are doing?

This might be a silly question but I’d love to hear others’ thoughts so please be kind! So as I understand the world of See, most people, those who haven’t met Jerlamorel or his children and who don’t work for the Queen, don’t have a concept for what it is to have the sense of sight and to move through the world using vision. Yet most people know that the Queen’s army uses horses and dogs to travel and guide them, and to find people. So do they understand that the animals are using a power that people don’t have? Or do they just think the animals are feeling and smelling their way through the world, as people do? How do they explain to themselves why the horses and dogs help make Temacti Jun such a formidable Witchfinder?
