Duchess is a large, blonde Labrador Retriever who belongs to James Stark.
Duchess is described as being a large, blonde, "bear-like" dog with a pink collared studded with spikes.
She transfers with James Stark from the Chicago House of Night to the Tulsa House of Night in Untamed. When opposition arises to her presence at the Tulsa House of Night, Stark says, "She's my version of a cat." This is later acknowledged when Stark dies and Duchess is seen "grieving just like a cat will who loses her vampyre" - by howling. After Stark's death, Jack Twist takes care of Duchess and becomes quite attached to her as she to him.
However in Awakened, she is heard mourning over Jack's death by howling.
