Interesting. Also, because one of the commands I taught Mateo when he was young was, "Not your concern," (i.e. "not your business" in the video.) Mateo is not reactive, in general, but living where we do, with so much stimulation going on constantly, sometimes there are situations where he becomes too engaged or aroused (i.e. an aggressive dog that is trying to challenge him, or cats that are teasing him...whatever). It's a good, calming command, as it were--- and he gets it, mostly. And we continue walking...
