Long life

The shape of a dog’s face suggests how long it will live. Dogs with sharp, pointed faces that look more like wolves typically live longer. Dogs with very flat faces, such as bulldogs, often have shorter lives.[

Dogs catching poachers

This is amazing.

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.
