by Claudine Zap This China policy is really for the dogs. Or maybe we should say, against them. The AP is reporting that Guangzhou, China, is instituting a one-dog rule. No exceptions, and no grandfather clause for households who already have more than one fluffy family member. There is a reason behind the madness: Many new dog owners don't spay or neuter their pets, and worse, tire of their dogs once they're no longer puppies.
