2 dogs die during Alaska's Iditarod sled dog race, prompting call from PETA to end the event

Two dogs died over the weekend during Alaska's annual Iditarod sled dog race, marking the first deaths during the race in five years and renewing calls to end the 1,609-kilometre competition that sees mushers and their canine teams traverse mountain ranges, a frozen river and sea ice — often during treacherous weather.

Bog, a two-year-old male on musher Issac Teaford's team, collapsed Sunday morning about 61 metres short of the checkpoint in the village of Nulato, a former Russian trading post located 937 km into the race across the Alaska wilderness. He died despite a veterinarian performing CPR for about 20 minutes.

A second dog, George, a four-year-old male on musher Hunter Keefe's team, also collapsed and died despite attempts to revive him, a race statement said.

George died on the trail about 56 kilometres outside of the village of Kaltag, which is 1,012 km into the race.

A necropsy did not determine a cause of death for Bog, and the Iditarod said further testing will be conducted. A necropsy on George will also be conducted.

Keefe, of Knik, and Teaford, of Salt Lake City, both voluntarily quit the Iditarod Trail Sled Dog Race on Sunday. Under the race rules, they risked being withdrawn by the race marshal otherwise.

The last dog to die during the annual race was Oshi, a five-year-old female on musher Richie Beattie's team, in 2019. At a post-race checkup, veterinarians found signs of pneumonia in the dog. She was flown to Anchorage for care but later died.

Both Keefe and Teaford are fairly inexperienced in running the Iditarod, one of the world's longest sled dog races. Teaford is a rookie and Keefe was in his second race after finishing 11th last year.

The dogs' deaths on Sunday prompted People for the Ethical Treatment of Animals (PETA), long the Iditarod's biggest critic, to call for race's end.

"The death count keeps climbing for dogs who are forced to run until their bodies break down, all so the human winner can get a trophy while the dogs get an icy grave," PETA Senior Vice President Colleen O'Brien said in a statement.

"PETA is calling for this despicable race to end."

PETA has claimed more than 150 dogs have died in the Iditarod, but race officials have never provided an official count of dogs that have died since the first race was held in 1973.

The organization conducted a protest outside the convention center where the mushers' banquet was held before the ceremonial start of the race on March 2 in Anchorage.

An Iditarod spokesperson did not immediately respond to a message seeking comment on PETA's call.
