We were waiting inside the bus that will take us to our hotel in Palo Alto when we saw this dog and his master. I think the owner was blind and this dog was his guide since they both have IDs. It amazes me how they know (the dog knew) where to stop and wait for their turn to pass in the pedestrian lane.
This remind o me of the dog in the movie Hachiko from Japan although the owner in the movie was not blind. It's just the way the dog obey and does things for his master. Dogs indeed are man's best-friend and in this case, an angel.
