This incident made national news. I watched it here in Charlotte. The dog owners were all tearful about their hero dog, who "saved their lives." However, having read the "facts" on this board, the dog was not a hero.
People like to have "heroes" and it sounds better to say "my dog saved our family" than "my dog was stupid enough to chase after a mountain lion, and we managed to scare him off".
Now they can make a hero out of the dog, the local paper will show photos and tell the story with a 'slight' bias, along with a photo of dog recovering surrounded by treats and get well cards 8^). Over the years, the story will get better and the dog will have become a legend...
Reminds me of a story in Yellowstone, I think back in the '40's or '50's. A lady was griping to the ranger how her beloved small dog wasn't able to run free without a leash, and how unfair it was. The ranger pointed out a sow bear sitting with her cubs playing in a tree, and explained that was one of the reasons that the leash law was absolutely necessary. "Oh, if that's all you're worried about" she said as she unsnapped the leash, "my (dog) won't hurt the bear."
And she was right. The dog immediately took off running full speed directly at the sow across the meadow, who appeared to pay no attention to him. Until he got right up to her, when she turned and gave him a swat that killed him instantly.
The woman, of course, sobbed uncontrollably and wondered why they allow such vicious animals to be in the park, and why they're not put down.
