Blake Griffin's dog is a violent menace -- so says an L.A. man who claims the Detroit Piston star's pooch bit the crap out of him at a fancy restaurant ... and now he's suing.
The man behind the suit is Emmanuel Aframian -- who claims he was dining at A Votre Sante restaurant back in June 2018 when Griffin's "vicious" dog attacked him out of nowhere.
Aframian says he suffered real injuries from the attack which required expensive medical care -- and he thinks Griffin should have to cover all the bills ... plus other damages.
