Huihu, from Chongqing city had been suffering from depression following her five pups being stillborn. Then one night, the Chiinese pooch came home with a tiny black piglet.

Her owner, Lao Yi, says that Huihu has since reared the little pig as if it were her own puppy, nursing her and taking her around for walks.

The piglet has been reported to have put on 2kg in weight from lapping up Huihu's milk.
