This is Dracaena in a quadrupedal dragon form. All of my dragons have a quad mode, a vestige of the ancient days when dragons were huge and feral. This form has many disadvantages vs. the smaller biped mode, which is why the quad mode is scarcely used any more. However, it does offer an increase in physical strength, which makes it good for hauling cargo over long distances (and personnel - in fact, some dragons have fold-out seats concealed in their dorsal plates!).
