A baby in Oklahoma is dead after being attacked by a Labrador retriever puppy.

Police say the baby was mauled by the Labrador at the boy's home when he was left unattended in a swing by the dog.

Authorities also say that the child's 17-year-old mother was so distraught that she had to be hospitalized.

The baby was killed at the scene, and the dog was put down.

The child's body was taken to the Medical Examiner's office. Cops say they will forward their investigation to the district attorney to determine whether criminal charges are warranted.

The dog will likely be put to sleep.
