I have lately been trying to "thin the herd". A few years back I could never bring in a NEW GUN without my little German Shepherd Kodi, ratting me out.
She literally would sit and stair and gun safe if I ever brought home a new one. She would sit staring at safe until my wife acknowledged her "oh Kodi is their something new in there?" That brat dog would then look over at me and I swear smirk and then walk away. She also did this with ANYTHING I brought in new.
She was a smaller shepherd from Germany [about 50 lbs].
