On Monday, January 24, Tracey Hurst's Good Odds Calvin, trained by Andrew Bell, was put down following an incident in race six (a 520 metre grade five event).

According to the NSW Greyhound steward's report, Good Odds Calvin checked off the heels of Spritely Ebony exiting the first turn, which resulted in the former falling.

As it fell, Good Odds Calvin collided with Ebony - seeing the former become unable to finish the race.

This incident resulted in Hurst's greyhound suffering a compound fracture of the left radius and ulna - forcing the owner to euthanise it.

It comes seven days after Darryl Dunnell's Takahi Katey, trained by Joseph Bertinato, was euthanised following a collision with Under The Beam.

This resulted in Takahi Katey, in her first race since February 19, 2019, suffering a compound fracture of the radius and ulna.

"The Greyhound Welfare and Integrity Commission has confirmed that greyhound, Good Odds Calvin, was euthanised as a result of catastrophic injuries at Nowra on Monday, February 24," a GWIC spokesperson said in a statement.

"The on-track veterinarian humanely euthanised the greyhound on welfare grounds, after it suffered a compound fracture of left radius and ulna with a poor prognosis for a full recovery.

"The GWIC is concerned that two dogs have been euthanised at the Nowra track within two weeks and both incidents will be analysed by the race injury review panel to determine the contributing factors and preventative measures.

"The commission supports any initiatives aimed at reducing racing injuries - such initiatives require an evidence base supporting their introduction.

"The GWIC works closely with UTS (University of Technology) and the industry Animal Welfare Committee to develop an evidence base.

"The commission's race injury review panel has determined that there are a number of contributing factors to consider when analysing the causes of track-related injuries.

"The race injury review panel meets monthly to analyse all catastrophic injuries and major II serious injuries to understand the contributing factors and make recommendations aimed at reducing the risk of injury to racing greyhounds.

"A report of the panel's findings is published to the Commission's website every six months."

In the past month alone, 10 greyhounds have suffered injuries at the Nowra Pinebowl - which has three inspections a week, including two on race day.

On Monday, Be My Friend (spike injury to left hind foot), Gitcha Quick (right hip), Zaviers Monaro (right groin) and Dads Nitro (right pin muscle) all suffered injuries.

The week before, following his collision with Takahi Katey, Under The Beam suffered injuries to the pectoral, gluteal and deltoid.

Two weeks before that, on February 3, Red Rufus (right dewclaw), Neddy Alexander (right thigh, left shoulder and lower back) and Brash An' Sassy (dislocated right hock) all suffered significant injuries.

In 2017, a study, authored by the UTS, found 80 per cent of catastrophic injuries were caused by congestion on track, which often happens as dogs bunch together on bends.

The report then made 11 wide-ranging recommendations to improve animal welfare to the sport's governing body Greyhound Racing NSW - including reducing race from eight to six greyhounds and the creation of straight tracks.

A GRNSW spokesperson added that whenever there are incidents on track, they are fully always investigated.
