Border collie herds tigers in South Africa

PORT ELIZABETH, South Africa

The dog, named Solo, is putting his skills to the test at a wildlife reserve. Solo's high energy keeps the tiger cubs in check.

Solo's owner says the dog has a strong bond with the tigers is because they've all been together since birth. Solo considers the cubs to be part of his pack.

He should enjoy being boss while he can, though. A fully grown male Siberian tiger weighs about 385 pounds.
