Here's a great working dog video with a guy that lost both his feet and is back at work.
"I am still rocking! For those who haven't heard, I was blown up, with my MWD, Axe, Feb 17th of this year. I lost both of my feet, and was back to work in July. ..."
If there's any doubters out there about the bond between man's best friend, this video is living proof. Also, look how happy that dog is after the sky dive!
