Something Happened the Other Night

Last night our insurance agent stopped by. As he pulled into our driveway, I put Kodi behind the gate in our dining room. After "agent" was in the kitchen talking to us for several minutes, sitting down at the table, I noticed Kodi was very calm behind gate and I decided to let him come into the kitchen with us. I asked Kodi to sit next to me and he was fine. I did notice that Kodi was using calming signals (licking his lips, looking away) which made me realize that he was "nervous" or upset about the situation. I was absorbed in reading the insurance papers and didn't realize that the agent, Ken, got up to use our bathroom. Kodi NOTICED. He jumped up and barked and looked like he was going to bite Ken in the "butt". He didn't. He got very close and then backed off. I blame myself for not removing Kodi when I noticed that he was using the calming signals. Of course, I put Kodi in a safe place again behind the gate.
