Dragons are more like fantasy-creatures or myth-creatures and there are no such thing in reality (did you know that in the Middle Age when they found the bones of dinosaurs, they thought that there were dragon bones?), so that's the reason for that they don't count as animals.
I think that no fantasy/myth creatures are allowed in this contest, only real animals, if I'm not mistaken.
