The Coalition for the Protection of Greyhounds has raised concerns about the number of deaths and racing injuries occurring at the Nowra Greyhound Track.
So far in 2020, figures show there have been two deaths, which is the third worst in the state.
The deaths included two, two year two-year old greyhounds which suffered compound fractures of their radius and ulna in eight-dog races.
Both were euthanised.
Meantime there have also been 44 injuries, of which eight were major.
National President Dennis Anderson says a UTS study has looked at ways in which track safety can be improved in order to reduce the number of deaths and injuries.
The study recommended that there should be no more than six dogs in a race and that the dogs should run on straight tracks.
