And then some dogs are simply heroic
This story (http://www.dagbladet.no/nyheter/2007/03/14/494986.html in Norwegian and too long to translate, but you can see the pictures) is about Taylor (left), the Aussie shepherd, who woke up his Mom (right) and wouldn't let her go back to bed until she'd checked the front door. There she found a confused elderly lady who'd been walking for miles, in her stocking feet, with an ambulator. It was well below freezing outside and the woman was thin clad with bleeding feet, so she'd have died by morning if Taylor hadn't woken up his Mom for the rescue.
