Love dogs. Love the Japanese even more for their highly bizarre gizmos. No other country has consistently amused and amazed the world with its weird and wacked-out inventions. Try topping this latest doggone idea--ringtones audible only to dogs, from Tokyo-based interactive content provider Dwango [PDF in Japanese]. Whatever were they thinking? Just in case you reckon this for a joke, Dwango's dubbed the download service very clearly as Inu ni shika kikoenai chakushinon. Translated, that reads: "Ringtones only dogs can hear." Take a bow-wow, mutts of the world. But since this is available specifically for DoCoMo's i-mode phones, only Japanese dogs need apply.
