In South Africa, man’s best friend is now poachers’ worst enemy.

To combat the illegal hunting of endangered elephants and rhinos, the country has trained an elite force of poacher-chasing dogs to parachute into wildlife reserves from helicopters. And the dogs are effective—one caught 115 groups of poachers in 18 months.

The organization behind this terrifying approach to conservation is a security tech company called Paramount Group. The BBC recently took a tour of the group’s Anti-Poaching and Canine Training Academy, and filmed some video of the dogs practicing. You can watch that video here.
