'Taxi Driver' Writer Scorsese Had a Real Vicious Dog ... Bit & Ate Part of Thumb!!!
Martin Scorsese might have the follow-up to his classic "Raging Bull" ... 'cause apparently, he's living with a raging dog -- one that maimed his longtime collaborator.
Paul Schrader -- a legendary Hollywood screenwriter and director -- spoke with Variety to promote his new flick "Oh, Canada," and revealed he had a fearsome run-in with Marty's dog which pulled a move worthy of a "Goodfellas" gangster.
The way Schrader tells it ... he went over to Scorsese's crib in December for dinner -- and, when he went to pet a little Scottish terrier, it went full Cujo and bit him, ripping off and eating part of his thumb!
