Last week, Dempsey went on a field trip to the airport, along with 21 of his "Big Dog" colleagues. It was quite a sight, seeing 22 dogs riding the light rail to the airport and then practicing their skills by the baggage carousels!
Dempsey did pretty well, with one exception: The quart-size Ziploc bag with containers of toiletries 3.4 oz or less. I told Dempsey that it doesn't matter if he thinks it's a dumb rule, he's still not allowed to rip open the bag and try to retrieve the toiletries one by one. Fortunately, we weren't going through security, so Dempsey didn't have to do any explaining to the TSA officer.
Obviously, we'll have to practice more to keep Dempsey off the "no fly" list.
