This dog is one of the biggest fighters we know!
McKenzie Grapengeter's dog will keep on trucking, no matter what the elements throw at her!
Abby, an eight year old mix braved a snowstorm after she got separated from her owner in Alaska.
But she turned up at the Grapengeters' doorstep, surviving a 10 mile walk in -40 degrees Celsius!
AND SHE'S BLIND!!!!
And the best part?
