Wow, great story; thanks for the link. Even if she had been well prepared it is the dog that saved her, since she was stuck at the bottom of the ravine. While I agree that she should have taken a cell phone, it is highly likely that she wouldn't have been able to get a signal in that steep, rocky location.

To cut her some slack, it is not easy to carry much gear when trail running. And while some basic stuff like a HeatSheet and firemaking gear would have been nice (if she had been able to find & utilize wood), signalling is what saved her. In this case the signal device was the dog.

This case is a good lesson of what Peter Kummerfeldt describes as a dangerous assumption: we often assume that in a suvival situation we won't be injured, that we will be free to move and act as needed. Good food for thought.
