As for the skulls, it's because the swear filter took away the "sh*t" from "sh*tzu."
For future reference, it's actually spelled, Shih-Tzu.
Yes, I had a feeling that there was something wrong with that spelling, but I was just commenting based on what she had written, and I didn't feel like bothering to search the proper spelling. But thanks, now I know what was wrong with the spelling.
