My Doberman/Alaskan Malamute mix dragged me off of my Magna V45 by my brake foot many years ago when I was leaving to go to work one morning. The poor dear just despised my motorcycle; after that she stayed put up until I left. Ruined the boot, damaged my pride, the bike had nary a scar...and like yours, once she saw saw she had me in her jaws she knew she had done wrong. Happily, I was laughing so hard I didn't scold her into submission over a natural instinct, i just knew to put her up when the scoot came out.
