THE world's first tour bus for dogs is being launched in London today.

The green number ‘K9' Routemaster bus will take dogs (and their owners) to some of London’s best parks and city centre dog walking spots.

Along the way, live onboard commentary discusses the capital's doggy connections.

The bus, launched by "More Than", is free for dogs and their owners, and will take passengers three times a day from Monday 16th - Thursday 19th January.
