Have mercy yes. And wild, if I leave the front door open, she sees her reflection in the glass of the storm door, and does this insane sideways gallop toward it, flicking her tail, like se will scare away her reflection, which only grows closer, and she takes off running.
I had a crazy dog once. My mother's apartment in Puerto Rico has a large corridor, with a glass wall in one of the ends. So that dog which we called Whiskey because of his color, would run fast, then slide all the way through corridor, until he hit the glass wall. He'd do it over and over again. It was a strong glass wall so there was no way he would break it, but my mother grew worried anyway, and gave Whiskey to my uncle who had a house with a yard for the dog to run free. At least he was close by and we could visit him anytime. Whiskey died a few years ago
He was always a crazy dog.
