Completely unrelated… my mom had a small dog when she was younger. The dog sustained a head injury at some point, and after that could only make right turns. If the dog wanted to go left, it had to turn 270 degrees to the right. In all other ways the dog was completely normal. But now I’m wondering if the dog wanted to lie on its left side, would it lie on its right side, roll into its back, and then settle on its left side?
