Trail of the Yukon

Trail of the Yukon is a 1949 American western film directed by William Beaudine and starring Kirby Grant, Suzanne Dalbert and Bill Edwards. It was based on a novel by James Oliver Curwood about a NorthWest Mounted Police officer and his faithful German Shepherd dog Chinook. It is part of the Northern genre. The film was popular, and inspired Monogram to make a series of nine further films starring Grant and Chinook.
