Beginning July 1, people in Guangzhou, China will be limited to one dog - and since the new regulation won't be grandfathered in, families with two or more dogs will apparently be faced with the decision of which one gets to stay.
The Associated Press reports that many other Chinese cities, including Beijing, have long had one-dog policies, with officials holding mass dog round-ups when they decide the dog population is too large or there is an outbreak of disease.
The AP report says "killing campaigns" - and rabies outbreaks - are common in China. More than 2,000 people die each year after being bitten by rabid dogs.
During a 2006 Beijing dog roundup, witnesses accused police of going through neighborhoods and collecting unregistered dogs from the streets, then beating them to death. In one county where three people had died of rabies, authorities killed 50,000 dogs, often clubbing them to death in front of their owners.
Dog owners are said to be formulating their plans for getting around the new regulations.
