What is wrong with this picture?

Here you see Abby, my Border Collie, on the wrong side of the fence. This temporary fence was erected to keep her out of the garden while new plantings took root. And once she jumped INTO the garden she began to bark and bark and bark. Why? Because she was stuck! It was easy for her to get a running start and jump in but she couldn't get herself back out once she was in there. Dogs!
