Shigure Souma

Zodiac Animal: Dog Shigure transforms into the dog of the Chinese Zodiac whenever he is hugged by the opposite gender or his body comes under a great deal of stress. Shigure is one of the oldest members of the Soma family. He is laidback and anything but solemn. He is somewhat of a pervert and as a writer of both romance novels and academic books. Occasionally Shigure shows that he has another side to himself. He can be surprisingly mature thoughtful and gives rather sage and insightful advice to Tohru Kyo Yuki and other characters acting like an actual adult. Source: Wikipedia
