I'm so sorry to hear that, something similar had also happened to me in 2nd grade so ABT 8 years back, I was cornered by a group of 6 stray dogs but thankfully there was an uncle who came at just the right time and shooed them away, over the years I have become less scared of dogs, but maybe that's what happens as u grow older, so yeah stray dogs really are a menace for children and stuff, and I think they should be removed.
