It's being organised by My Lovely Horse Rescue of Edenderry and Kildare.
Protesters outside the Dáil are calling for transparency and accountability from the Department of Agriculture.
It's been organised by Edenderry and Kildare's My Lovely Horse Rescue, and follows the launching of an investigation into animal welfare at a plant run by Shannonside Foods in Kildare.
Operations at the plant have been fully suspended, after footage emerged of horses being severely mistreated in an RTÉ Investigates programme.
Co-Founder of MLHR, Martina Kenny, says they're not asking for much from the department:
