Flight 51 through security was a new experience. I walked through and then Cricket followed which then generally has them do a quick pat down to Cricket as her harness sets off the alarm. This time, they decided they needed to take the harness off and run it through security. They also wanted to take Cricket off to check her out. Nope I said - assertively. Not necessary or okay to take my dog away! Not going to let go of that leash. Sometimes they respond like they have never had a guide dog go through security. Coming home on Flight 52, they were aware that I did not set it off so they just needed to check my dog. I have not had them inspect every part of Cricket and her harness so thoroughly before. The man behind me commented on it also. Cricket was so happy thinking she was getting all this extra attention. Both flights we had our favorite kind of plane: the divider between first class and bulk head stops at the seat so Cricket has a little extra room to stretch out.
