6m old big breed suddenly barking at other dogs

I have a 6m old bullterrier that up until recently, spent the work day on a farm with other dogs and farm animals. She plays well with them. She also done fine when we take her to the pet store. However, recently, she goes full Mohawk when other dogs walk past our house. We live in a very dog friendly areas where there is an entire community around walking dogs. I dont want her to spook the neighbors nor to feel any sort of aggression or anxiety toward other dogs. I have been walking her at night recently because im nervous to have her around the neighborhood dogs. Any suggestions?
