Three New South Wales greyhound trainers caught up in the Four Corners live baiting scandal are facing jail terms after pleading guilty to serious animal cruelty offences.

Telopea trainer Ian Morgan, who was captured on covert cameras using a live possum on a lure to train one of his dogs, Cee Cee Quoted, has pleaded guilty to one count of serious animal cruelty over the incident and now faces up to two years in jail.

In January, cameras filmed Mr Morgan deliver a live possum to the Londonderry property of Zeke Kadir, a figure who is well known in the industry for breaking-in inexperienced dogs.

Kadir was filmed tying the live possum to a lure and allowing the animal to be mauled and eventually killed by one of Morgan's greyhounds.

Morgan brought the possum himself to Kadir's property and was seen releasing it from a cage from his car and providing it to Kadir to be tied down and killed.

Kadir has pleaded not guilty to a number of animal cruelty offences.

The ABC understands that the NSW Director of Public Prosecutions has elected to prosecute the case.

If found guilty, Kadir faces up to five years in prison.

Brothers John and Tony Cauchi have pleaded guilty to a combined 15 counts of serious animal cruelty and live baiting offences.

John Cauchi was captured on cameras using a rabbit on a leash to entice and excite a greyhound he was breaking in.

They will both be sentenced on December 2.

The trio are the first trainers to plead guilty following the broadcast of the Four Corners program in February.

A number of greyhound trainers in Queensland have also been charged with animal cruelty offences.
