Reuben McNulty was just one month old when he was attacked in the early hours of Sunday, November 18 at the family's home in the village of Yaxley, near Peterborough in Cambridgeshire, England.
His parents' Staffordshire Bull Terriers named Fizzy and Dotty both attacked him. He died in the hospital om Thursday, almost 4 weeks after the dog attack.
The boy's parents Dan McNulty, 31, and Amy Litchfield, 28, were arrested on suspicion of child neglect and released on bail. Detectives say the baby's death is not being treated as suspicious.
