Nastassja, a two-year-old trained by Garry Streatfield was assessed by a veterinarian after finishing fourth in race five on Saturday, October 17.

According to the meet's steward's report, Nastassja came together with another greyhound after the start and had heels checked. After the race she was found to have a severely fractured offside hock and was euthanised after consultation between the on-course vet and connections, Hastings River Greyhound Racing Club president Rex Nairn said.

Mr Nairn said he had viewed recorded footage of the race and watched the stewards replay after the race to check for interference.

"It ran the circumference of the course about 600 yards fine and coming off the grass of the track, was ready to be caught by its trainer but fractured a hock," he said.

"It is fairly unfortunate, it's very sad. Dogs do bump each other a lot because some run wide and some run next to the rail but trainers try to keep their dogs as fit and healthy as they can.

"In terms of safety the course is cambered, the track has been returfed and there's a safety rail on the inside rail which has great big pads if a dog hits the rail."

The incident is the second fatality this year after Karnak Bale, trained by Rosana Streatfield, fell awkwardly to the racing-surface during a meet on July 25.

Karnak Bale was assessed after the race, found to have nearside and offside forearm fractures and euthanised.

Coalition for the Protection of Greyhounds national president Dennis Anderson said on-track deaths can be reduced by implementing safer tracks with an emphasis on straight tracks and six-dog races.

"Greyhounds run at 60km per hour and deaths and injuries are inevitable. Most incidents occur at track curves where the dogs bunch together, and broken legs are common," he said.

"On Friday night the NSW greyhound racing industry held the Million Dollar Chase. The money should be directed towards improving track safety and rehabilitating injured greyhounds."

Mr Anderson said CPG is advocating for reform of the racing industry with safer tracks, whole-of-life tracking of a greyhound, a reduction in breeding, funding of sanctuaries and increased penalties for mistreatment.
