シルヴィアーナ

The pet dog of Risa. Initially the pet of a cruel breeder, she is rescued by Risa and Yuuichi. She is quiet and shy throughout the game, partially due to her relatively low intelligence. She is part of a rare and valuable breed of dog, and thus it was necessary for Yuuichi to spend a lot of money to free her. [From Wikipedia] Her breed is a golden shih tzu.
