Sadie, the black-and-white dog, is the very hyperactive creature we adopted 18 months ago from a shelter. Because she insists on running away when turned loose, she's had to be kept either in the house or on a tie-out ever since we got her. She's so in-your-face, jumping all over other mutts to greet them, that most dogs won't come near enough to play with her.
Recently someone dumped a mongrel in the neighborhood that has, for the most part, taken up residence here. She isn't afraid to play with Sadie. We call her Annie, as in "little orphan".
In the above picture, Annie has something Sadie wants. I wonder what it is?
I use an air mattress back at my cabin in the woods; I don't leave it aired up all the time, because I don't sleep back there very often; when I'm going to spend a night, I air it up with a hand-pump.
The pump makes a squeaking noise that drives Annie crazy. Here's a video that shows her in action. Turn on your sound.
