For me it was framing "holding a dog preemptively close when nothing happens" as a bad thing and indicator of an "untrained dog" that made me disagree with your characterization.
My dog is wonderfully trained. A wonderfully well behaved little princess everywhere except when a strange dog approaches her in public and sticks their nose in one of her soft spots.
Since she got attacked by another dog, she retaliates aggressively to dogs who were not under proper control and who were allowed to invade her space without consent.
I am proactive about the potential of unresponsive owners with "trained dogs" failing to properly control their dogs.
That doesn't reflect my dog being untrained. The reflects the number of untrained dog owners out there.
