A small Sheltie puppy. She is very smart, and also very loyal to her friends. For dogs, even for Shelties, she has very high IQ. Therefore, usually she is able to understand what the discussion is about, even without actually understanding it.
Three words would describe her the best: Smart, loyal and cute. She will always understand most of what you're saying, even if you think she doesn't.
Inner parts, brain and lots-to-be fur.
No history, but more info about Shelties can be found here: http://en.wikipedia.org/wiki/Sheltie And here's a nice quote: (09:52:07) Marcus Duralus: (The Muffy (level 99 puppysaurous) has been discovered!)
