Oh my word, Beth! I agree...he should be reported.
I understand about perceptions of breeds, etc; but, I've had negative experiences (UNprovoked attacks) from both a Pit bull and a Shephard! It's very difficult now, not to let that show through when I meet either of the breeds

And, Abigial is in obedience class with Shephards (thank goodness we only have one class left!) - and the trainer keeps telling me she'll pick up my vibes. But, I have heard so MANY horror stories, right here, on YT, where larger dogs have attacked and killed smaller dogs - for no reason!
