person A: I was walking my dogs the other day and a guy came out with his dog off leash.  The dog ran up and freaked out both my dogs.
person B: That must have been scary. It could have gone really badly.
person A: Yeah_comma_ I was really worried.  My bigger dog got really protective of the smaller one_comma_ but thankfully they didn't actually get into a fight.
person B: I hope the owner knows better next time.
