APD spokesman MJ Thim said Hudson was still missing Saturday afternoon, adding that the dog's race gear includes the number "61" on its side.
A dog from a team set to run in the Iditarod Trail Sled Dog Race was found after getting loose before the ceremonial start of the race in Anchorage.
Since its inception in 1973, the race has fended off activist criticisms, touting its slogan, "The Last Great Race", to an audience that grew well beyond the participating Alaskan towns of Willow and Nome. It's the last trail ride for one popular musher.
The disappearance happened about two hours before the ceremonial start began with mushers taking a short sprint with their teams along downtown Anchorage streets.
The dog was last seen heading toward a nearby neighborhood in the downtown area.
The Iditarod Race kicked off this weekend in Anchorage, AK, sparking protests from PETA, whistleblowers, and other activists who want to save dogs from dropping dead in the archaic event. The teams will trek to Willow for Sunday morning's official start on the 1,000-mile run to Nome. Last year Groovey, a 3-year-old dog dropped from musher John Baker's team on the trail and flown back to Anchorage, escaped its handler and subsequently died after being hit by a auto near Northern Lights Boulevard and Bragaw Street.
Sixty-seven teams are vying for a total purse of $500,000. Race organizers said they couldn't prove Seavey did it and didn't sanction him.
