China are now following up the “One Child” policy with the “One Dog” policy according to the BBC

Authorities in China’s capital Beijing are to implement a “one dog” policy for all households as part of a campaign to combat rabies, state media has said.

Owning a second dog will be outlawed in much of the capital, and anyone keeping unlicensed dogs faces prosecution.

It seems that Rabies is the biggest cause of death from infectious deseases in China. However, if Bird Flu keeps mutating maybe we will see a “One Bird” policy in the future.
