Dogged by demands of the day? Hounded by the hubbub of crowded urban life? Then, how about Japan's latest - a canine oxygen bar, a pure air kennel breathing new life into the meaning of pet posh. The Air Press, which has over 20 oxygen bars across Japan, has opened its first oxygen bar exclusively for dogs in Tokyo. Placed in an air-tight cylinder, operators say the pure oxygen environment offers an extra pick-me-up for the pooped pup. "If you do not live in an urban city, you can let your dogs run around a huge place like in the highlands, freely. But in the Tokyo area, Japanese home space is very limited while dog walks are only occasional. So it will be very difficult for dogs to stay in good condition without this kind of extra health support," said the owner of the dog oxygen bar "OWND cafe relaxation salon" Tsuyoshi Hirano. Four-legged consumers were unavailable for comment, but owners say the dog bar is barking up the right tree. "My dog may not be tired but he is usually lethargic. After he comes here, though, he is enthused and barking with vigour," said Umekichi Sakon, one of the dog owners who often brings his beloved pet there to offer a health boost. A thirty minute oxygen treatment costs for 2,100 yen (18 US dollar).
