A dog called Eclipse just wants to get to the dog park, so if her owner takes too long finishing his cigarette and their bus arrives, she climbs aboard solo and rides to her stop.
The black Labrador and her owner, Jeff Young, live near a bus stop in Seattle.
Jeff said Eclipse sometimes gets on the bus without him and he catches up with her at the dog park three or four stops away.
Bus riders said she watches from the window for her stop.
A Metro Transit spokesman said the agency was delighted that a dog appreciates public transit.
