"one dog" policy

Hello! I think many of you know about the law in China which limits a family to have only a single child to stop the growing population. Well, there's going to be another restriction in Beijing, China. On Wednesday, November 8th, Chinese authority announced that families living in Beijing are allowed to have only one dog per household. Part of the reason for this is to extinguish rabies (in Japanese,"kyouken-byou"). In China, problems related rabies are serious. In 2004, 2,651 deaths from the disease are reported in China alone. Also, only 3 percent of China's dogs vaccinated against rabies. Anyone keeping dogs without licence will be punished. It is a good thing that government is working hard to stamp out such horrifying disease. I heard that once you were bitten by a dog with rabies and get ill, there's no cure. In other words, he or she won't survive. However, on the other hand, what would happen to the unlicenced dogs which are caught?? The dogs are certainly slaughtered or killed. Although it is said so in the law, I think it is against ethic. What do you all think??
