Lifford Greyhound Stadium in Donegal will close down following its meeting on Saturday, August 17th.
It's understood that 25 full-time and part-time jobs will be affected.
Track officials have cited the lack of support from the Irish Greyhound Board as the main factor in its decision to close down.
The venue was part of a nationwide review of the greyhound industry with those findings expected to be published in September. It’s almost a year since the review was first initiated, as part of the Irish Greyhound Boards strategic Plan 2018-2022.
Separately, the Irish Greyhound Board had promised reforms in the wake of an RTÉ investigation earlier this year which revealed that thousands of greyhounds were killed in 2017 because they weren’t fast enough.
