Keepers at the Jiaozuo City Zoo in China were worried that an orphan monkey was being bullied by bigger primates so they gave it ... a guard dog!
After being forced to intervene to save its life several times, they settled upon the trained canine, named Sai Hu, and are happy to report that it has been very successful.
"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 jump on the dog's back and holds on tight. The alpha male monkey has been really unhappy since we sent in Sai Hu. He tried to organise several ambushes on the little monkey, but they all failed because of the dog," said a zoo spokesman.
