Great Dane Power

Hi,
several years ago our pair of Great Danes dragged the wife on her
stomach through a snow bank and across the road and through another
snow bank and halfway up a front yard chasing a cat!
I would imagine that 2 Danes would equal 1/2 horse? yet I can stop my
lathe with one hand, go figure.
I guess the dogs could not have dragged the wife around for 8 hours
though....mush, mush.
