Blooding will shock industry: Shorten

Reports of animal cruelty and the "blooding" of dogs would revolt many in the greyhound industry, opposition leader Bill Shorten says.

A number of greyhound trainers in Victoria, NSW and Queensland have been implicated in live baiting, which the RSPCA believes is entrenched and systemic in the industry.

Labor leader Bill Shorten said an aberrant minority appeared to be involved, and the broader industry would be shocked by the reports.

"I am sure that most people who own greyhounds and breed greyhounds and work in the industry would be alarmed, revolted and disgusted," Mr Shorten said in Melbourne on Wednesday.

"I think this is people who care about both the industry and the welfare of greyhounds versus the few people who, at first report, seem to be conducting themselves in a revolting manner."

Mr Shorten said he wanted authorities to reassure people that the greyhound industry had a focus on animal welfare.
