Yikes! Where did that come from?

Harmonie was doing school and she colored the snow red. I asked her why she had colored it red. She said, "Lots of dogs died, so there's lots of blood."
Whoa! Where did that come from? I don't even know why she would think about that.
Then she said, "The dogs were freezing because the owners didn't let them inside. It's a sad story."
