The health and welfare of the horse is of paramount concern to the Alcohol and Gaming Commission of Ontario (AGCO) and to members of the racing community. An effort to monitor weather conditions and how it will impact the racehorse is in keeping with this mandate.
The AGCO has advised its Official Veterinarians and racing officials at all racetracks to remind participants to take the necessary steps to protect the horse in warm weather conditions.
Dr. Adam Chambers, AGCO Senior Manager of Veterinary Services, suggests that any concerns about weather conditions impacting racing should be shared with horsepeople representatives, racing officials, track management and the Official Veterinarian.
