I was staying at a hotel the other night and I had my (now six month old) Jack with me. He was on his leash and I was trying to get him to follow me into the room. I called his name and whistled a few times but he just kept trying to go check out a pine cone on the ground nearby.
Just then a lady wandered up and asked about Scott. We talked for a minute, then she asked me the funniest question ever: "Is he deaf? He doesn't seem to hear you."
I could only laugh and reply, "No, he is just a Jack."



My Shih Tzu, Katie has that problem on occasion as well.
