@jaxosk26 The single most effective thing I ever did was train my dog to stand behind an umbrella. The immediate sight block calmed him, prevented access from the other dog, and just generally de-escalated the situation immediately with no other action required until the idiot owner and their "friendly" dog fucked off.
Otherwise I just found a shirt and leash sleeve that simply said "DO NOT APPROACH" white text on red background the best advocating tools. If I had to talk to someone I'd call out "Don't let your dog make contact, mine is super contagious, very sick!" this was the single most motivating thing for other owners far more than asking them to recall or telling them by dog wasn't friendly. Their fear of some mystery virus was far stronger than that of my dog actually being a risk on his own, haha.
In serious situations I also found "I'll kick your dog if it approaches us" was super effective but always opened up arguments, so use at your own peril![Stick out tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
