The Humane Society of the United States has been concerned with animal welfare resulting from specific events, particularly the three-day equestrian event, at the Atlanta Olympic. Representatives were on hand for check-ups throughout the event, and have suggested modifications be made to the event to improve horse welfare. Research into heat and humidity control has also been identified as an potentially important aspect of this event. In the Atlanta Olympics, 7 of the 90 horses competed experienced an injury of sorts, including dehydration, minor cuts, bruising, pulled ligaments, or a bone fragment. No State of Georgia welfare laws were broken during the event.
