i suppose most dudes recognise the protagonist as more of a dragon than a goat, and there are also other dragons in Mokken as well. There isn't that much of a different between a furry dragon and a goat except for the fur colours and skull structures.
Although it is partly convenience, so we can repetitive scenes explaining your own backstory to every other characters, werewolf story is mostly self-contained so there might not be many call-backs until much later on. :p
