That's why I have 5 dogs, they exercise each other. One dog would be more trouble to me too.Just went out and measured the goat shed so i can figure out where i want the windows. Threw stick for the dog. I am wishing i got a less energetic dog. She needs so much exercise, it tires ME out. And if she does not get it, then she really becomes a pest. Husband already played frisbee with her. It should not be a full time job just exercising the dog. We had a Shepherd before but she was out in the pasture a lot. She would run back and forth in the pasture chasing cars that went by. No cars going by here. Sigh.we need a mechanical ball launcher.
