Genuine question. I was browsing the dragon tag and I'm wondering what's the official requirements for a character to count as a dragon. I've seen so many characters tagged as one when they lack everything related to dragons. No horns, no wings, no scales, no tail, no fire... Having just a muzzle or being feral or having sharp teeth makes it count as a dragon? I understand that dragon is sort of a loose term and people gets creative with their sonas and hybrids, but at some points it gets ridiculous.
Just some examples:

What makes these a dragon and not a cat or feline? It feels like anything characters whose species is sort of ambiguous just gets slapped with the dragon tag. There's gotta be a line somewhere, or else everything can be tagged as a dragon.
