Dog owners in Shanghai will soon be limited to one dog per owner.

China’s dog population continues to grow and now the government there has decided to limit it. According to Bloomberg News, Shanghai is moving to limit residents to just one dog per household.

The population of dogs is causing headaches for the city government which is banning certain breeds because of an increasing number of attacks under new rules passed by lawmakers, according to a statement released by the municipality today.

Shanghai’s population may have reached 23 million people last year as more migrants moved to the city, China Daily reported Feb. 23. Dog ownership has also risen dramatically with incomes in China, which passed the one-child policy in 1979 to limit its human population.

The incomes of the people of Shanghai continues to grow and that has increased the appetite for dog ownership. The problem is that the city, according to the report, has 600,000 unlicensed dogs. It raises the question: Should the government limit dog ownership? How many dogs are too many?

Owners who are caught with more than one dog could face a fine of $152.
