Dmitri was Daniel's dog and beloved companion. His mother was the Sykes family dog. Cecilia gave Dmitri to Daniel when Daniel was nine. He lived at Grayson Hall.

Dmitri was always at Daniel's side when he was in Yorkshire. When Daniel was away at boarding school, Dmitri and Cecilia commiserated with one another in their longing for Daniel.

Dmitri was the loyalest of dogs and travels with Daniel through time.
