Isabelle (しずえ?)is a dog that debuts in Animal Crossing: New Leaf. She assists the player in their new role as the town mayor as their secretary and assistant. She is also the twin sister of Digby, who works and stands at the front entrance to the Happy Home Showcase.
Isabelle is very clumsy and absentminded and dislikes confrontation. Despite this, she is respectful of others and is very friendly. Being open-minded and friendly, she is very keen to make the town a better place to live, by encouraging the player to do tasks and Public Works Projects throughout the town. Like many other secretaries, she can be hard on herself when she is side-tracked. Isabelle has shown sides of gratitude and affection to the player, especially on Valentine's Day and is even hinted on having a crush on the player regardless of gender.
Isabelle is a nearsighted bright yellow dog who resembles a Shih Tzu, which her Japanese name, Shizue, is a play on. Her head is also shaped like a bag of bells, hence the English name. She has a happy appearance with rosy cheeks and with a white fur patch on her tail and around her mouth. She wears a green checkered vest with a white top and a red ribbon underneath with a navy blue skirt. During fall and winter, she wears a yellow cardigan instead of a vest. Her hair is tied up with a red elastic with bells attached which actually jingle as she walks.
She wears different styled clothes on special events that are held around the town; for example, she will wear a flowery shirt during the Fireworks Show and a Santa-style shirt on Toy Day.
