Cameras and pictures are weird.
- Digital cameras can make their own edits, tweaking things. Part of the rope is made to look like a shiny green viper by the camera all on its own.
- Pictures with no context can give the wrong impression. This is not Shadow-dog throwing up, but rather opening his jaws to grab what is actually just the rope.
No, Shadow-dog is not possessed. He’s a good dog!
Meanwhile, I know people all over this country who are being attacked by Satan’s minions, for real. Prayers for them, please: Hail Mary…
ARISE! LET US BE GOING! 
Praying!
Praying!
