I am smiling,
laughing and generally happy to see your Katie's bed in the making. I'd make one for Pequina, our poodle, who sleeps IN my bed but she would never use it. She makes up OUR bed to her satisfaction, and generously leaves me, Mama, about 1/3 of a queen-sized bed. I wanna come back as MY dog. Hope your Shih Tzu will use hers. It will be a winner, I know. Have fun knitting for her.
