That reminds me of my faithful pitbull/dingo mix, Prudence, who made me laugh for almost sixteen years. When she was around 4, I accidently discovered a command that she immediately responded to - "Go away."I was sitting on the floor reading a newspaper or magazine, and she came up for her usual dose of affection, and stood on my paper. I kiddingly, and in a playful voice, said, "Go away, Rudy. Go away."
To my somewhat bemused amazement, her ears dropped, she looked directly at me for a second, as if seeking confirmation of my meaning, and then turned and walked a few feet away, turned around and laid down. I had never taught her that command.

I'd love to know if Prudence had been with Phil for her entire life, or if she could have learned this command prior to meeting Phil. I'm wondering because I remember the day I brought home my dear Jake from Multnomah Co. Animal Shelter, back in 1995. All my dogs had always enjoyed the front seat in my car, so on the day we left the shelter I opened the passenger door for Jake and in he jumped...and kept on jumping, over the center console, and into the back seat.
During our many years together, Jake would ONLY ride in the back seat. Clearly he had learned this before he came to me. I figured he would eventually make his way up front, after which he and I could have meaningful conversations without my having to turn my head and speak to the back seat. But this would never be.
The thought just occurred to me - maybe he didn't like my driving skills, and this was a self-preservation tactic. In which case, dear Jake, I completely forgive you.
