You've just helped to make someone elses dog even more fearful of larger dogs.
When around other dogs I expect focus on me and my commands. My dog doesn't enjoy playing with other dogs outside the home and frankly most people lack evena rudimentary understanding of canine body language and I will never put my dog in a situation where he feels he has to attack another.
We do not go to dog parks etc. We go to obedience training, we are around a dozen or so other dogs every obedience class and we work around them. They are not there to be played with, barked at nor are we there for my dog to carry on like a pork chop.
Dogs are NOT human. They do NOT require play time with other dogs, in fact my dog now is happier than the farm dog who before he went to the farm was attacked at dog parks, he was heavily dominated and now has many issues with other dogs because of it.
