All those competing at this month’s July Show at Tattersalls Ireland must comply fully with HSI anti-doping rules.

Horses taking part in a competition must be healthy and compete on their inherent merits. The use of a prohibited substance might influence a horse’s performance or mask an underlying health problem and could falsely affect the outcome of a competition.

The equine anti-doping rules of The July Show at Tattersalls are the National Rules of Horse Sport Ireland, in particular, without limitation, National Rules 1.2, 10, 11, 12, 14, 15, 16, 17, 18 and the Appendix, as may be amended from time to time, and these National Rules are and shall be construed as the rules of The July Show at Tattersalls and apply to and are effective and binding on all participants at The July Show at Tattersalls and by participating in Horse Sport at the national level, all participants shall be deemed to have agreed to be bound by and to comply strictly with the applicable National Rules.

The list of prohibited substances has been compiled to include all categories of pharmacological action. The July Show at Tattersalls complies with the Horse Sport Ireland Equine Anti-Doping and Equine Controlled Medical Rules (see link) https://www.horsesportireland.ie/wp-content/uploads/2025/07/HSI_EADCM-Rules-effective-27th-June-2023_FINAL.pdf and with the FEI Veterinary Rule on Prohibited Substances. The list can be found at: http://www.FEIcleansport.org.   

The presence of a prohibited substance constitutes a doping violation – if the horse has a positive anti-doping violation, the published result for that horse on the day of the anti-doping test will become invalid and the horse will show as Eliminated.
