Theresa is a very friendly wolf. Her original form is a black Chevy. She lives with her sister, Cecilia(a Nissan), and a good friend, Michael(a Ram truck). Theresa cares about Bernie and is often the one asking if she's okay every time she's silent on walks. She often checks up on Bernie up at the corner. She at first didn't know who Baxter was, but after some time, she realized he was a bully. Theresa is very Catholic, and she is often inviting Bernie to sit with her in the pew at Old St. Pat's
