Xue became a full-time dog walker after he resigned from his job in the IT industry. Now, he runs a pet care service business with his wife and friend in Haikou, the capital city of South China's Hainan province.

The pet care service's prospects are good as pet lovers are increasing in China. Moreover, dog walkers will be in demand because they can provide dog walking services when pet lovers are busy.
