This is DEFINITELY a Basenji Chi mix and NOT shiba. (Only the example of a Shiba is a Shiba for those who might be confused by the example pics.)
Basenji has the white feet, white tip on tail AND the white spot at the nape, and the curled tail. does he/she "talk" ? My chi Basenji has an unusual talk that everyone loves. Some who know more about basenjis - a couple in the neighborhood who have 2 - call it the Basenji yodel.
