Dogs are cheetahs’ best friends, too

Here’s a fascinating story: some zoos have been using companion dogs for decades to help their cheetahs relax. The dogs’ reassurance makes it easier for the cheetahs to breed.

Introduced when young, a dog and cheetah bond and grow up together. But it’s a one-time thing; if a companion dog dies, the cheetah does not bond with another one.
