A celebrity dog breeder had his lip hanging on by a thread … after a French bulldog viciously bit him in the face.

Ronnie Wright of Famous Owned Bullies tells … he needed 11 stitches this week when an adult Frenchie at a client’s house lunged at his face as he went to kiss it.

He didn’t have much time to stop the gush of blood from his mouth … telling us when he walked into the house to wash it off another Frenchie pounced onto his leg — though he managed to kick it off.

Ronnie tells us when he looked in a mirror, his lip was hanging off his face and he was rushed straight to the ER.

Currently, he’s still super swollen … meaning it’s hard for him to talk, eat, or sleep. He has been dealing with dogs his entire life and Frenchie’s for 16 years and never had a single incident.

To rub salt in the wound … he’s gotta have reconstructive surgery when his stitches come out … ’cause the bite ripped out a piece of his lip cartilage.

Ronnie, based in Carlsbad, San Diego, has built a successful career for himself … entrusted by clients including Snoop Dogg, Wiz Khalifa, Jamie Foxx, Selena Gomez, and more — so the attack undoubtedly comes as a shock.
