Greyhound welfare advocates are calling for more transparency after figures emerged that at least 500 dogs have been sent to the US for rehoming as the racing industry continues to breed far more dogs than are needed.

Australia is one of seven countries where commercial greyhound racing is legal – New Zealand, Mexico, Ireland, the UK, US and Vietnam (where no races occur) also allow the sport.
