This documentary was originally released by the Department of Defense as part of its "The Big Picture" documentary series highlighting different aspects of the armed forces. This video is from a set of brief clips highlighting service schools of the US Army in Europe - this particular one highlighting the Quartermaster Corps Dog Training Branch in post-World War II Germany.
Please note that this film is available in the public domain and is not copyrighted. Free sharing and use of this film is permitted. Some of the footage in this is the same as in some of the other "Big Picture" videos. I guess they were quite fond about recycling the same footage.
