Authorities say a dog attacked and killed a 4-year-old girl and injured the child's mother at a home near Sturgis.

The St. Joseph County sheriff's department says the family had recently gotten the Doberman or Doberman mix before Sunday's attack in Sherman Township. The girl's mother tried to protect her and was hospitalized with injuries to her head and hands.

Names of those involved weren't immediately released. The attack is under investigation and the dog was taken away by animal control.
