The Shiba Inu is the smallest of Japan's native breeds, an ancient type of dog once used to flush birds and small game from brushy mountain slopes. Wartime hardship and disease nearly wiped it out, and today's Shibas descend from three surviving regional types. Compact and muscular, with a fox-like face, pricked ears, a curled tail and a plush double coat in red, sesame or black and tan, most weigh roughly 16 to 25 pounds.
Many Shibas are alert, confident and clean, almost cat-like in how they groom themselves and choose when to be affectionate. They're also independent, with strong prey drive and a tendency to bolt, which matters in a suburb with squirrels, rabbits and deer. Patient, reward-based training suits them, and a Shiba that has learned the household routine can be a deeply loyal companion. Each dog varies.
