During WWII, one of my uncles worked in the Richmond, CA shipyards. One day a ship came in that had captured a Japanese ship and taken prisoners. On board was a little dog and some puppies. My uncle brought home one of the puppies in his breast pocket for his children. My cousins had that dog (named Judy) for nearly 20 years afterward. They thought she was a mutt, having never seen a dog like her before, but every time they encountered a Japanese person from the old country, that person would get very excited when they saw Judy. I think Judy was a Shiba Inu (or a cross).
