A photo of a man mistreating a dog that were uploaded on the Internet Thursday by a netizen surnamed Liu in Fuzhou sparked public outrage.

The photo showed a man riding a motorbike on a highway while he was dragging the dog behind him with an iron chain around the animal's neck.

"I rolled down my car window and asked the man to stop. However, the man speeded up and drove away," Liu told the Straits Newspaper, a metropolitan daily paper in the capital of East China's Fujian province.

"The dog couldn't bark due to the chains around its neck, and its four legs were bleeding," Liu said. "The speed of the motorbike was about 50 km per hour at the time."

Some netizens left messages at Tianya.cn, a popular online bulletin board, to rebuke the man's brutality. Some doubted the man was a dog thief. Other furious netizens demanded a search for the man.
