"The thoroughbred industry needs to address the issue of the legs being too weak. The Stampede has done everything they could do to prepare the track, to change the rules so the wagons are not smashing into each another.” (Source)
How the chuckwagon races are run, as well as standards for other events at the rodeo, have been greatly overhauled in the last year since six horses died at the Stampede's 2010 edition. Two died of heart attacks, two were destroyed after suffering injuries and another broke its back from bucking too hard. The sixth died after experiencing health difficulties 40 minutes after a chuckwagon race. One change made in the wake of those deaths sees veterinarians implanting a microchip in every horse that is scheduled to compete in the chuckwagon races.
