341 TRS opens third specialized MWD training lab Published Jan. 11, 2022 By Agnes Koterba 37th Training Wing Public Affairs JOINT BASE SAN ANTONIO-LACKLAND, Texas -- The 341st Training Squadron, home of the Military Working Dog program for the Department of Defense, opened its third specialized training lab here Jan. 5, 2022. The new lab focuses on explosives detection, and allows canines and their handlers to train longer and reduce risk of injury due to environmental conditions. “This year is huge for our program. I've been here since 2009. We've been begging for training labs. And let me tell you, if it were not for the folks that are here, we wouldn't be where we're at today,” said John McKinney, 341st TRS MWD course chief, at the ribbon-cutting ceremony.
