Butt dialed 911

We accidentally butt dialed 911 when putting together furniture and not soon after the police show up. The dispatcher lady heard in the background banging and yelling. She thought it was a domestic violence situation and sent them out. We were putting together furniture and I was yelling at my dog who was getting in the way. Do cops get scared when they get called out to these kind of calls? I was actually surprised they were concerned enough to show up too.
