A 2008 Equine Veterinary Journal (EVJ) publication examining dehydration in working horses was summarized and printed onTheHorse.com on April 24, 2008, prior to its actual publication in EVJ. It was reviewed and approved by the researcher. The complete publication (in which Dr. Joy Pritchard was first author) was titled “Validity of indicators of dehydration in working horses: a longitudinal study of changes in skin tent duration, mucous membranes, and drinking behavior.”

Recently, Dr. Olin Balch, a member of Veterinary Committee of the American Endurance Ride Conference (AERC) contacted Pritchard and TheHorse.com with committee concerns that the summary could be misinterpreted, especially where endurance horses are concerned.

Balch and Pritchard coauthored the following clarification.

Pritchard said, “My research studied changes in physiological parameters in 50 working horses pulling carts or carrying loads at moderate speeds in Lahore, Pakistan, over a period of 5 hours. While these results could be generalized to similar horses in developing countries, the conclusions are not directly transferable to any other horses, endurance or otherwise
