Myrna Mountweazel is the Spiegelman's dog in the book Paper Towns by John Green. In the book she is often mean to Margo, growling and making noise when she gets near Margo. For example, Margo wasn't able to get the keys to her car (which were in a safe under her parents' bed) because Myrna Mountweazel would have made noises and woken her parents. In Margo's journal, she wrote a story about herself, Quentin Jacobson and Myrna. However, instead of being a regular dog, she was a magical puppy who could talk.
