Mae took off Thursday after its Jamaican team's sled tangled with another sled on the trail between Rohn and Nikolai, and was still on the run Friday when spotted Friday.
"There are other people in the area where Mae was lost and who are looking for her. They have seen her but she is a bit timid," Jamaican musher Newton Marshall said in his Facebook fan page.
Marshall had to be scratched from the race because he arrived at the Nikolai checkpoint without the same canine cadre he had when he set off from Rohn.
The Anchorage (Alaska) Daily News said there have been instances in which lost sled dogs survived for a few days before being reunited with their teammates.
