Researchers at the University of Saskatchewan’s Western College of Veterinary Medicine are seeking healthy, client-owned horses to take part in research on equine respiratory disease, according to a statement on the school’s website. 

"We are interested in studying respiratory diseases, such as heaves, in horses," the statement reads. "Establishing reliable reference ranges for our horse population will be an essential foundation for our future equine health research and a significant contribution to diagnosing and treating equine respiratory disease.

"In order to move this program forward we are looking to recruit client-owned horses for the period of May 2013 through August 2013," the statement says. "Results from these horses will be used to establish normal reference ranges for our local horse population
