Police said the child was visiting a home in the 5200 block of Pinebrook Drive in west Charlotte Tuesday evening when the homeowner's pit bull charged her inside the home.
A police report said the child suffered "severe lacerations."
Police, medics, and multiple animal control officers arrived on scene, according to neighbors.
"My daughter said her neck appeared to be covered in blood, and the dog had blood on his face as well ... she didn't so much as whimper. I assume she was really in shock," said Deborah Spann.
Animal Control officers seized the dog from the property while the girl was taken by ambulance to Carolinas Medical Center Main.
Other residents said it is not the first time the pit bull has escaped.
"I saw the dog escape out," said Pyxa Vongxay.
Vongxay lives across the street from the home and said the pit bull had attacked another dog on in the neighborhood.
"I hope they'll be able to understand the point of being able to secure their dogs properly," another resident said.
