The infant is at UC Davis Medical Center with cuts to her head, cheek and chin.
Turlock police did not identify the girl or her family, but did say the injuries are not life threatening.
Officer Steve Rodrigues said the girl had just been given food by her mother who left the room and that's when the dog attacked. Rodrigues called the attack a tragic accident, not criminal behavior by the mother.
Juanita Curtis, the owner of the apartments where the family lives, said tenants are told animals aren't allowed. "No dogs, no animals, because of something like this. Especially pit bulls, I don't like them," Curtis said.
But another young mom living at the same complex has no problems exposing her children to her pit bull. "I know signs of aggression," said tenant Jessica Decker. "I leave my dogs around the babies all the time. It doesn't scare me."
The dog is being held for 10 days at the Turlock Animal Shelter for health reasons and to be observed for any further aggressive behavior. Rodrigues said the dog will either be euthanized, or adopted out to another family. He said the dog will not go back to the family that is now dealing with dog bite injuries.
"They voluntarily surrendered the dog, they have no ownership of the dog. It currently belongs to the animal control shelter," said Rodrigues.
