Third Calgary Stampede Chuckwagon Horse Dies

An outrider horse competing in the GMC Rangeland Derby chuckwagon race at the Calgary Stampede in Alberta, Canada, died Friday following a pulmonary embolism.

The Thoroughbred was the second chuckwagon race horse to succumb to a cardiac issue, and the third to die at the event in six days. A chuckwagon team horse died from a cardiac episode following a race on July 1. On July 7, another team horse was euthanized on the track after it broke a leg during the race (read more).  

"Handlers were leading the horse to the barn area when it collapsed," said Stampede spokesman Doug Fraser.

Event veterinarians determined the horse had a pulmonary embolism, Fraser said. This condition typically occurs when a blood clot dislodges and settles in a horse's pulmonary artery, blocking the blood supply to its heart.
