You guessed it right....
I got the same treatment at LAX getting off a LanChile flight from South America.
As I rounded the corner of the jetway......and as I was the 2nd-3rd one off the plane, out of nowhere jumps a uniformed customs agent who says to me...."Sir we are testing a new dog and I would like to put this package on your luggage to see if he hits on you".
I said sure...no problem. The dog walked right past me BTW....like I figured it would. This was just an attempt at profiling to see if "I" was going to be spooked by the whole thing...thus warranting a secondary inspection.
