Watch this rather different video in which an Australian postman introduces us to all of the dogs on his route. In Australia, the grass/lawn from the letterbox to the road that you see him riding on is owned by the Council/Government and not by the home owner, which is why they are allowed to ride there. There are some profanities in the video, You have been warned.
