Terri Springer is Artie's mother on Dog City. A springer spaniel, Terri is a confident businesswoman and single mother, a forceful female who attracts the attention (and affection) of Eliot Shag. She also serves as the new inspiration for Rosie O'Gravy, the animated love interest of Ace Hart, when the original model, Colleen Barker, moves away. Her puppet is later recycled in Mopatop's Shop as Mrs. Flibbertigibbet.
