A small, agile dog that copes very well with mountainous terrain, the Shiba Inu was originally bred for hunting in Japan. After WWII the Japanese put down their guns, and instead decided to use this industrious dog for mail delivery. Now all postal letters and small packages are delivered by Shiba Inu in Japan. Unfortunately America doesn't have enough Shiba Inu to institute a similar mail delivery program, but you can still show your support for this wonderful breed of dog by buying Shiba Inu postage.
