What's the difference between a dog and a wolf?
That was the question visitors to a zoo in central China asked themselves at the weekend when they found a lone dog of indeterminate breed loping around an enclosure signposted as housing wolves.
"That's a dog, not a wolf," a visitor to the Wuhan Mt Jiufeng Forest Zoo in Hubei province says in a video posted online and widely shared.
The dog-wolf appeared to be the latest addition to a long list of improvised wildlife at Chinese nature parks that has included inflated toy penguins and plastic butterflies.
But the zoo told Shanghai-based news portal Thepaper.cn that there was no attempt to deceive visitors.
