My dog Sydney is playing with some dogs, and they're wrestling in a big pile, standing on their hind legs and packing together. The bunch is getting packed tighter and tighter, until Sydney is lost in the middle and it looks dangerous, so I step in and break them up.

But it's too late, she is hurt. She falls down on the ground with her head flopping, and then the skin has pulled back from her throat, leaving it translucent like it's made of clear plastic. I can see right to the bones in her neck, which are clearly sheared between her head and her body.
