No. Lt. William Putney trained the Marines' 2nd & 3rd War Dog platoon in Quantico. The first War Dog Platoon was trained by a Hollywood trainer (presumably in California). If there was a LA or MS school, it could be US Army which is pure speculation. I'm unaware of any US Navy or Marine Corps training camp in those states (but I'm no expert on that subject matter). As for training to sniff out people, part of it is genetics (my belief) and part of it is diet. To sniff out Japaneseicon, they would require people of Japanese descent who are fed a traditional or Japanese military diet. I'm unaware of any Nisei who played search dummy either.
