Another note for the Orion's Dog files (my SF work-in-progress). Dogs can lie
Yahzi was accomplished at lying. I saw him try to blame a crime on the cat once. He'd trick other dogs into having a fit and then act innocent. On a camping trip he wanted a sandwich I was eating; when I didn't give him any, he started staring off into the distance; when I stared the same way, he made a lunge for the sandwich.
