LONDON (REUTERS) - The world's 'first' tour bus designed especially for dogs took some pampered pooches on sightseeing tours of London in January.

Tour bus promoter More Th>n Doggyssenti>ls said over 160 dogs enjoyed a ride on the K9 bus over the three days (Jan 16-19) of the one-off event, with the route concentrated on London's dog-walking hot spots.

Dog owners joined their pets on board the traditional London bus painted green and sporting new seat covers, and the rides were sold out every day, More Th>n Doggyssenti>ls told Reuters in an e-mailed statement.

The tours started one day earlier than scheduled due to the event's popularity, the organisers said.
