bulldog attacks owner

hey guys, so this video has been floating around the internet. the supposed back story is this man attempts to feed the mans dog, man gets angry and hits the man, the man then beats up the guy, the guy getting beat up then gets attacked by his own dog.

My thoughts are that the man in the red shirt is not the owner of the dog, most likely watching it or something. The dog is also built pretty damn big, I would guess theres an outcross in that EBD somewhere. 

wanted to see what you guys thought about it

I would be very surprised if the guy who got bitten is really the owner of the dog!
