From HuckFunn: Hobby the dog is indeed this man's best friend.
Via Daily Mail:
They say a dog is man's best friend – and this footage proves it.
Captured on CCTV, this is the moment a heroic canine came to a shop keeper's rescue to fight off an armed robber.
The footage begins in fairly mundane fashion. A man is seen tidying up as the Mont D'or tobacconist in Manosque, France gets ready to close for the day.
