Pneumonia caused the death of Oshi, the 5-year-old sled dog from 2019 Iditarod musher Richie Beattie's team, according to a report from Iditarod officials.

The preliminary findings from a board-certified veterinarian were announced in a news release from the Iditarod Trail Committee Thursday night. While the necropsy determined the reason for the dog's death, it did not find the cause of pneumonia.  

Further examination is needed, including testing of tissue samples and for viruses. 

Oshi's death was initially reported March 16, after the dog had been transported to Anchorage for care. Beattie completed his Iditarod run two days earlier. 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, March 15 for further care. She died at 6:37 p.m. the next day at an Anchorage animal hospital. 

In the release, the ITC stated the necropsy study should be finalized in 30 days.
