The Chambersburg Police Department welcomed Scout Troop 128 to the station for a K9 demonstration and article search.  During this time Pfc. Hinds spoke about the history of the K9 unit at CPD as well as dog care.  The scouts had great questions on the structure of the work day/home life balance as well as on general K9 information.  Mattis, of course was on hand to handle all the pets after he demonstrated obedience work and what an article search looks like.
