A newborn boy died Monday night after being mauled by the family pit bull while police were responding to a domestic violence call at the home, MyFoxDFW.com reported.

The baby's father, Barnett Bruce, began arguing with the child's mother, Jessica Oxford, shortly after Oxford brought the child over, police said.

Three-month-old Rayden Bruce's grandfather was holding the infant while the parents argued. Police were called after the argument escalated into pushing. When police arrived, one officer took the mother's statement outside while another spoke to the father inside.

The baby had fallen asleep in the grandfather's arms, so he went to put the sleeping baby on the bed and came back to talk to his son, police said. A short while later, the grandfather heard noises from the bedroom and went to investigate. That's when he found the dog had attacked the child.

The baby's father grabbed the child and ran outside, and police called paramedics, Erron said.
