Bao, the teacup chihuahua, liked to nestle inside his crate with a warm rice heat pad his owner made for him. As soon as he heard the microwave chime, his tail wiggled in excitement for bedtime. He would run to his bed waiting for his owner to wrap the heat pad in a blanket. Bao would then cozy up in his cave, burrowed in his blanket ready to call it a night.
