A 5-year-old sled dog has died after completing the Iditarod Trail Sled Dog Race.

Oshi, a female sled dog on musher Richie Beattie's team, died at 6:37 p.m. Saturday at an Anchorage animal hospital, according to a news release from the Iditarod Trail Committee late Saturday night.

Beattie and his team finished the race at 10:01 p.m. Thursday in Nome. Veterinarians with the ITC discovered signs of pneumonia during a post-race examination of the dog. Oshi was stabilized and flown to Anchorage on Friday for further care. 

"Sadly, Oshi passed away the following day," ITC officials wrote in the release, which listed a preliminary diagnosis of aspiration pneumonia.

According to the ITC, Beattie has been withdrawn from the race per rule 42 of the official race rules. The ITC says he "is fully cooperating with Iditarod officials."

On Thursday, he was named the rookie of the year for being the first rookie to cross the finish line in Nome. It was unclear on Saturday whether that title would be passed on to Ed Hopkins who finished just after Beattie. As of 10:19 p.m. Saturday, Beattie had been removed from the official race standings on Iditarod.com.

Rule 41 of the race states that all dogs are “under the jurisdiction of the Race Marshal from the time they enter the staging area at the start until 72 hours after they have been released by ITC veterinarians or 48 hours after the final musher finishes.”

The ITC release states a necropsy will be conducted to determine the official cause of death.
