Help

I’m making a steampunk, action teen to adults Wizard of Oz game but I can’t think of a Titel and a breed of dog for Toto

Well I’ve thought of either a Doberman, Newfoundland oder a schipperke

I need a Titel that fits the Oz Titel and theme of the game (Steampunk) and a dog breed that is strong and guarded

Can Du please help me think of a Titel and a breed of dog for me
