I think I may have a dwarven dog.
- She's short.
- She's very stocky.
- She's unexpectedly strong.
- Her size makes her look like an easy target, but she can take on a dog several times her size. And win.
- She has white chin markings that make me think of a beard.
- She likes to dig for treasure (although admittedly not exactly the dwarven idea of treasure).
