New South Wales Premier Mike Baird has hit back at criticism from the grey-hound industry, calling some practices "horrific" and "inhumane".

As NSW greyhound industry heavyweights held crisis talks at Wentworth Park in Sydney, Baird said trainers were still livebaiting, even after the scandal was exposed last year.

"I'm a big advocate of small government that keeps out of your way, but that doesn't mean government stands back and allows cruelty to animals on a widespread scale," he posted on Facebook.

"My instinct on this, before the inquiry's report was handed down, was that we would find a way to reform this industry. But then I read the report. I didn't need to read it twice.


"There was nothing hasty about it, or this decision. If you read the report for yourself, you will see that the Government had little choice but to take this course of action."

Senior members of the Greyhound Breeders, Owners and Trainers Association vowed to convince Deputy Premier Troy Grant and other National Party members to help overturn the ban, which will come into effect on July 1 next year.

Dubbo Greyhound Racing Club president Shayne Stiff said the industry would attack the decision in the courts and on the floor of Parliament.

"Hopefully Baird leaves it with Troy Grant and we can get a fair hearing with him," Stiff said.

"He's ruined the lives of thousands of people. Political action, legal action; any action we can take, we will."

Stiff also reacted strongly to accusations of livebaiting and the industry's inability to rehome thousands of greyhounds after they retire from the track: "That was in the past ... we've moved on from that."

Greyhound authorities have announced racing would resume in NSW tomorrow under increased surveillance, with an enhanced swabbing programme, more stewards and vet teams - and more security at the tracks.

One of the key vets to give evidence about some of the most shocking cases of cruelty towards greyhounds expressed "extreme surprise" at the controversial move to shut the industry down in NSW.

Leonie Finster, who raced grey-hounds between 1980 and 2000, was a key witness in the Special Commission of Inquiry into the Greyhound Racing Industry in NSW.

Finster said Baird's decision had shocked her, although she couldn't see any other way to fix the problems.

"Whatever it is they do, there is a culture that you are never going to change," she said. "They haven't even included all the graphic detail. The industry has been in denial. They still practise methods that were the go in the 1960s."

Finster said she had come across shocking cases of mistreatment of greyhounds.

Some of the worst included the work of so-called "muscle men", untrained surgeons who would perform painful, "Depression-era" style treatments for injuries to the racing dogs.

New Zealand's greyhound racing body is defending the sport as it is practised here after the announcement it would be banned in New South Wales and the ACT after a livebaiting scandal.
