Norm and I use the magnetometer gate only since the circular “naked” scanner would require me to give up Norm’s leash and lose positive control of my dog, something I can refuse. So just short of the magnetometer gate I put Norm in a sit stay and suggest to the TSA agent my proposed solution. They always agree. When directed by the TSA agent, I walk through without Norm but with the end of his leash. That allows me to clear separately. Once the TSA agent directs me, I then call Norm to walk through.
Norm wears metal ID tags and has a metal carabiner on his neck so he usually sets off the alarm, but not always. I tell the TSA agent that they can pat Norm down and that he’s very friendly. The only danger they face is Norm possibly licking them. What I find humorous when Norm sets off the alarm, they yell out, “Male assist!”
Sometimes they want me to take off Norm’s service vest or leash. I refuse both of these requests. TSA protocol does not require it and if I took the leash off, I would lose control of Norm, something I will not do in this chaotic and legally consequential environment.
