柴犬
The Shinshu Shibas possessed a solid undercoat, with a dense layer of guard-hairs, and were small and red in color. The Mino Shibas tended to have thick, prick ears, and possessed a sickle tail, rather than the common curled tail found on most modern Shibas. The San'in Shibas were larger than most modern shibas, and tended to be black, without the common tan and white accents found on modern black-and-tan shibas. When the study of Japanese dogs was formalized in the early and mid-20th century, these three strains were combined into one overall breed, the Shiba Inu. The first Japanese breed standard for the Shiba, the Nippo Standard, was published in 1934. In December 1936, the Shiba Inu was recognized as a Natural Monument of Japan through the Cultural Properties Act, largely due to the efforts of Nippo (Nihon Ken Hozonkai), the Association for the Preservation of the Japanese Dog.
