Calls for an end to chuckwagon racing at the Calgary Stampede were prompted after six horses died in the very popular event.

According to the Calgary Humane Society and media reports, a total of 73 horses related to chuckwagon racing have been either killed or euthanized since 1986.

As a result, officials with the annual rodeo have said there will be a review of safety surrounding chuckwagon racing.

The Stampede has repeatedly faced calls from animal rights advocates to ban the chuckwagon racing event due to the number of horses killed.

Mike Bellisle is rodeo chairman at this week's Manitoba Stampede in Morris, one of Canada's biggest rodeos, which also features chuckwagon racing.

Bellisle wouldn't comment on the Calgary Stampede situation but did say that competitors in their rodeo events take great care to ensure the welfare of their animals.

"These guys care. We care about our animals and we're all deeply connected to livestock and in many cases, they're treated like pets or even better than pets."

Bellisle says, like all rodeos, the Manitoba Stampede has a veterinarian on-site and all the animals are checked every day for any health issues that may arise.

"Anything suspect is isolated and if they need to be held out for that day or the entire weekend then that's just the way it goes. Those steps have been in place for years already and it's common practice for all rodeos."

Meanwhile, officials are hoping the weather cooperates and the rains stay away for the next few days. Track conditions are in good shape for the rodeo events, according to Bellisle, and they're ready for a fantastic weekend of racing and rodeo performances.
