Dogs gone wild

So, our one neighbor's dog Sadie (we'll call it a pit bull, although I think it is a mix) attacked our other neighbor's dog Max (mini schnauzer) last night. Sadie jumped through the window, broke through the screen and ran to our neighbor's yard and tried to eat/maul little Max! The owner tried to break up the fight and in the process got her own hand chewed apart. They were finally able to spray the dogs with water and break them up. 3 police cars and an ambulance later, everyone will live to see another day.
Now I am terrified to let Hercules out in front of the house. Luckily we have a fenced in yard and he's pretty content there. If that had been my dog I think I'd be holding a grudge. But it seems the two neighbors have made amends and there's no bad blood between them. Max is recovering with 3 wounds and some stitches.
