Zoo keepers have given an orphan monkey its own doggie minder to protect it from bullying by other animals.
"Whenever the baby monkey gets bullied, he dashes up and drives the others away. And the baby monkey is also very smart. Each time he smells danger he runs to the back of his dog bodyguard and hangs on tight," said a zoo spokesman.
"Since we sent Sai Hu in, the alpha male monkey has been very unhappy. He tried to organise several ambushes on the little monkey, but they all failed because of Sai Hu," said one keeper.
