JACKSONVILLE, FL (CNN) - The family of a newborn boy is grieving after he was attacked by the family dog.
Investigators said the newborn was alive for just four days before it was mauled by a pit bull Sunday night in his Jacksonville, Florida home.
The Department of Children and Families is now investigating the parents for possible neglect.
The baby's mother said she only left the child alone for a few seconds when the attack happened.
"It's sad," said neighbor Michael Shannon. "It's really sad."
Shannon is a father too, and said he can't imagine what the parents are going through.
But he's also a pit bull owner and worries this attack will continue to give the breed a bad name.
"I have a pit bull," he said. "He's the sweetest dog in the world. I have a two-year-old. He plays with it. It really depends on who raises the dog."
Now as investigators are trying to figure out what happened, Shannon said parents just need to be more cautious with young children and pets.
"It's sad. I mean, people need to raise their dogs better."
The child's father said animal control put down the dog Monday morning.
