Two companies have announced they are ending sponsorship arrangements with greyhound races.
The moves by FBD Insurance and Barry's Tea come in the wake of last week's RTÉ Investigates programme on the greyhound industry.
The programme raised animal welfare issues relating to the overbreeding and subsequent treatment of greyhounds.
In a statement on Twitter this evening, FBD Insurance said it supports over 100 community events and organisations with very significant annual funding.
"Our only sponsorship of greyhound racing was a small sponsorship arrangement with Kilkenny Greyhound Stadium," it said.
"Following the recent RTÉ Investigates programme, FBD has decided not to renew this. We look forward to the implementation of urgently needed animal welfare measures by the Government."
It is understood that FBD's deal with Kilkenny Greyhound Stadium consisted of €1,300 sponsorship for a small number of races.
Meanwhile, also on Twitter ,Barry's Tea this evening posted a message saying it was withdrawing its support of a race in Cork.
"We were saddened and horrified by the recent revelations of the RTÉ Investigates programme, which raised concerns over the treatment of dogs within the greyhound industry in Ireland," it said.
"On reflection, we have decided to withdraw our local sponsorship of the annual race in Curraheen Park, Cork."
In a statement, the Irish Greyhound Board said it noted Barry's Tea decision and thanked it for its sponsorship over the years.
"The IGB continues to engage with our sponsors on our strong commitment to the welfare of racing greyhounds, including an additional number of measures approved by the Board at a special meeting on Friday, June 28th, 2019," it said.
"The IGB is now arranging for the implementation of these schemes. The welfare of greyhounds remains a priority for IGB and we will continue to build on the reforms within the sector over the last number of years."
