Occasionally Baby will bark a slow but steady cadence of very big woofs. When i go look she is laying on the bed apparently wishing to be waited upon.
Sometimes when Jack is sitting deep in thought she will quietly approach from his blind side, stretch her neck out over and above his neck and start air humping. Sometimes he senses what she is doing and gives her a very sharp bark of "Stop it!" Sometimes he does not notice and she seems very pleased with herself when she is done "I'm THE Lab".
She also does it to Tina who at 14 is really the queen. Tina will be sleeping and when she senses what baby is doing she gets up and trots away. Baby looks soooo disappointed.
She also barks at Jack when he is curled up on the dog bed by the computer. She will bark at him, nudge him to move , and sometimes he barks back. Her eyes get wide and she backs up. Jack just grumbles, gets comfortable again and goes back to sleep.
I sometimes sense I am being watched and look out the corner of my eye to see Baby hunched vulture like staring at me. If I ignore her she barks. Which amuses her as I usually startle. She then comes over and presents her head to be scratched. Maybe she does not reign supreme, but she gets by.
