This is the moment fearless wolves tremble in terror as they catch a whiff of a zookeeper who had just been feeding the tigers.
Bizarre footage of the encounter at Puyang Central Zoo, in Henan Province, China, shows the normally confident predators cowering in the corner of the enclosure.
As keeper Zhang Nana calls to them the pair as seen shaking in fear in the corner as they try to stay as far away as possible.
It later emerged that Zhang had just come from feeding the zoo's Siberian tigers and the smell of them terrified the wolves.
Zhang is heard saying in the 7th April clip: "When I said, 'I've brought you some chicken, come on, you two!' those wolves just curled up in the corner trembling."

The two wolves, nicknamed Dodo and Suosuo by fans, have only been at the zoo for six months and are usually looked after by another keeper.
And Zhang, whose job is to also film daily streams of the animals, says she only stops by to give them food.
But because she spends most of her time with the tigers, their scent tends to linger on her clothes and it apparently terrified the wolves.

One picture shows Zhang giving one of the big cats a belly rub.
In another, she is seen sitting on a bench at the tiger's enclosure with a younger feline sitting in her lap and playing with her arm.
She said of the wolves: "I've never hit or frightened them. I rarely even go near their enclosure – I just toss them food and leave."
Zhang added: "Honestly, I found it both frustrating and funny. I feed them often, and yet they're still scared of me.
"It's probably because I spend so much time with the tigers that I carry their scent.
"Other staff can approach them without such a reaction."
Zhang has been a keeper at the zoo since April 2018 and became a full-time tiger cub nursery keeper three years ago and now cares for four abandoned tiger cubs.
She joked: "These days, I'm not just a keeper, I raise tiger cubs. I smell so strongly of tiger it's like I've been marinated in it!"
And to avoid causing unnecessary stress to poor Dodo and Suosuo, Zhang said she would not visit the wolves anymore.
