Let's see. Pearl was flown here from GPA - GO. The then director of the program labeled her a spook.
One of the top 10 worst spooks to ever come through their program. Her words, not mine.
Her airline crate was bungeed closed so she could not possibly escape from the crate. She wore a harness and a collar. She was personally attended by the pilot (also a greyhound owner).
When she got to this end, we rolled her into a closed off room the airport let us use and broke the crate down around her. Then we carried her out to the car and locked her in the crate I had in my car. I drove all the way home without stopping, put the car in the garage and shut the door before I even opened the car door.
That was just to get her home. The next 10 months were spent feeding the phantom dog we called Pearl. Did we ever see her? No, not unless we forced the issue. I can't speak for anyone else's dog, but yeah.......mine is a spook!
