Wild animals are no match for the "Dog Bark" patrol
The "Dog Bark" patrol is on the job at Glacier National Park, notifying wildlife managers and herding mountain goats and bighorn sheep to keep them away from strangers. Officials say the wild animals are attracted to salt that drips off vehicles, and they pose a danger to people in parking lots who could get too close and provoke an attack.
Rangers tried using shotguns with non-lethal ammunition, sirens and whips, but they say dogs are better. The canines are already being used in other parks to keep the peace between humans and wildlife.
