Meet the Big Dog

You have to see this guy in action to believe him.






The Big Dog carries four backpacks. Looks like two guys in a robot suit.

Second picture: The Big Dog keeps running along into the shadow.







Closeup of the rear legs--no guys in the suits after all.







Some big meany kicks the Big Dog...but the Big Dog cleverly sticks his leg out and recovers anyway.







The Big Dog walks up hill; through snow; over rocks.
