A Rottweiler killed a black bear cub, according to police.

The dog, Max, was in an outdoor kennel but got out when the cub wandered onto the property Tuesday and right into the Rottweiler's path.

Max's owner built the pen in July after the 5-year-old pet caused the death of a neighborhood dog.

Teri Daubner told The Daily Record of Parsippany, N.J., that Max was simply protecting his owners. She worries that township officials will decide her dog is a danger.

The New Jersey Society for the Prevention of Cruelty to Animals is investigating.

Daubner said the bear's mother came into the back yard and dragged the cub's body into the woods about two hours after the little bear was killed.
