A dog on its regular morning walk has, for several months now, flatly refused to pass a particular driveway on its usual route, coming to a full stop, sitting down, and waiting to be walked around the block the long way instead.

The driveway itself appears, by all human accounts, entirely unremarkable. The house behind it is a tidy brick veneer, late-1990s build, fronted by a matching brick fence and letterbox, with a garden bed currently coming into full spring bloom — pansies, daffodils, and a scattering of other bulbs pushing up along the border. Nothing has ever visibly happened there.

More curiously, in the seven years she's lived nearby, the owner confirms she has never once seen a resident, a visitor, or any hired help at the property. The lawn is kept, the garden beds are weeded and replanted each season, and the hedges stay neatly trimmed, yet no car has ever been seen in the driveway or parked on the street outside, and no lights have ever been noticed on at night.

"I used to try and coax him past it," she said. "Treats, extra enthusiasm, walking a bit faster like that would help. Nothing. He just sits. Looks at me. Waits."

Eventually, the owner stopped asking why and simply began factoring the detour into the walk, adding, by her estimate, "about ninety seconds" to the total route, every single day, indefinitely.

"I don't know what he knows," she said. "I don't think I want to know, honestly. He's very sure about it, and he's never wrong about anything else, so I've just decided to trust him on this."

Neighbours along the alternate route have grown used to seeing the pair pass at the same time each morning, several offering their own theories over the months — a previous bad experience, a particular scent, an unresolved disagreement with a now-absent dog — none of which the owner has been able to confirm or rule out.

"At this point it's less a mystery and more just part of the walk," she said. "The long way is the way now. I don't even remember which way was originally shorter."
