Mine slept most of the time. When they weren't sleeping they were outside playing. It was pretty loud with all the fireworks, music, and kids playing, but mine didn't care. Later after everything was wrapping up there was a drunk lady walking down the road(we have no street lights and I don't think she should have been walking in her condition) and I was standing in my doorway as she stumbled by. A couple cars that were leaving the same party tried getting her in the car, that is when my male GSD started barking. He usually doesn't bark at anyone, but this was his I mean business bark. I'm not sure if it was the drunk lady of the people trying to get her in the car that rubbed him the wrong way.
