Actually, the majority of mountain lion attacks happen when humans go on hiking trails exactly like she was on. She was unprepared to protect herself, or her dog. In celebrating the heroism of the dog, we should always remember that she was an idiot.

Since 1986, there have only been 19 verified mountain lions attacks in the state of California, not what your radical enviro buddies propaganda says.
