Is he high or drunk?
Usually when these happen the owner was too far away and didn’t already have the dog trained to listen to them above anything else, but dude was 2 feet away. I’m literally wondering why he doesn’t grab the dog by the collar and take them inside once you see they are probably gonna fukk the dog up some way, but this idiot literally did that and then let the dog go.
Easily the owner’s fault. Train your damn dog to recall every time you say so, if you not gonna train that reactivity to strangers out of them
