Both were cared for immediately on the track but the medical team found there was no option for treatment and all three horses had to be euthanized, Stampede officials said.
The Calgary Stampede called the incident “upsetting” and said it will be initiating a thorough review process surrounding chuckwagon safety following the recent deaths.
“This is as upsetting to us as it is to our community, and is challenging for us. The Stampede’s commitment to the safety of animals and the conditions of their participation in our events is paramount to our values and brand integrity,” the release said.
“At this time, we don’t know what form that process will take, and we ask for your patience and understanding.”
The incident happened at the Calgary Stampede on the final night of races just after 9 p.m. Sunday.
The incident happened in Heat 8, resulting in a no time. The final heat was delayed several minutes while officials were sent to the field to assess the crew involved. Tarps could be seen from the infield.
On the chuckwagon broadcast, the announcer said: “There was an issue in heat number eight, down the back stretch, and we’re not going to show it to you.”
