A pet dog in China has been miraculously found 1,500km from home and reunited with her owner three months after she went missing.

September the Labrador was lost on August 13, at a beach in Qingdao, in eastern China’s Shandong province.

According to her owner, surnamed Gao, the dog walked out by herself while playing in her garden. By the time she noticed, September was already missing.

She checked the surveillance footage from a nearby beer festival and discovered September walking away with another dog and its owner.

Gao never gave up the search for her pet.

She toured animal shelters in the city and kept looking for online posts that might help her find her beloved pet.

Gao also travelled to other cities whenever she saw dogs that looked like hers.
