A 10-year-old Connecticut girl was in serious condition at Bridgeport Hospital after being mauled by a pit bull, News12 Connecticut reported.

Glaribel Rodriguez had to undergo extensive plastic surgery to her face, leg and abdomen, according to her father, Alberto Rodriguez.

Police said the 70-pound pit bull, which was being watched by the Rodriguez family for a friend, originally attacked a 7-year-old boy when the two children were playing with the dog.

“One of the kids hit the dog in the face and that’s why [it] got really angry,” Alberto Rodriguez told News12 Connecticut.

The girl was attacked when she tried to intervene, according to police, who said the pit bull was not vaccinated. It was under a 14-day quarantine.

Bridgeport Police Chief AJ Perez said the pit bull will have to be euthanized.
