You take bus No.3 and get off at the north gate of the old city. Walk 50 meters north and you will find Xianghe Shopping Center. There is an alley opposite. Cross the bridge and the dog market is just to the north of the bridge. It's not very big. I suggest you go there at the weekend. It's quite complete Then go to some pet hospitals in Beiyuan Street, where there are also dogs. Take bus No.2 at Beiyuan Street!
