Conan the praying dog folds his paws in prayer alongside a Buddhist
priest at Shuri-kannondo temple in Naha city, Okinawa province,
Japan.
The eighteen month old long haired chihuahua stands up in prayer
when the temple priest performs his sutras.

Apparently, Conan also prays before going out for walks, or before
feeding time.
Conan was named after the mystery writer, Arthur Conan Doyle.
