Thought people might enjoy this; I've been in Tokyo for the past week (half work, half sightseeing) and followed the signs to a little tiny dog shop and grooming parlour in the Harajuku dsitrict. They had this bike on sale, designed for carrying little dogs!! It costs around €450 so is not exactly cheap but I loved the red colour and compactness. I can see a cavalier or two on that crossbar dog seat!!
