In this June 2, 2018 photo, greyhounds swim for exercise at the Macau Yat Yuen Canidrome in Macau. Asia’s only legally regulated greyhound racetrack, a centerpiece of Macau's gaming tourism history, is to shut its doors in July, 2018. After rallying for years to shut the Canidrome, notorious for cruel conditions, animal right groups are now seeking to find homes for 533 greyhounds abandoned in kennels on the premises.
