Interesting approach.
Luckily I’ve not had to deal with people aggression in any of my rescue or personal dogs.
I have one dog who grumbles when insecure and to other people, it would look like it’s growling *at* me when actually, it’s growling out of anxiety over a particular stimulus.
That dog gets calm reassurance and then is moved to where I wanted it to be, in the first place.
Only a fool starts a fight with their own dog over such things.
What it *looks* like and what it really is are often wildly different things.
