Boss dude goes off to the Smokey Mountains to go backpacking. He says I can't go because dogs are not allowed in the back country, although I could prove to be very useful in the woods.
This dog is Lizzy.
And this dog is Chaos. His back leg was swelled up a little when he was found, but he still followed boss dude 20 miles or so in the back country to be rescued.
Lesson learned, just because you have a radio collar, it does not mean you still can't get lost.
