What happens if your dog attacks another dog at a dog park?

If your dog does get into a fight, try to remain calm and use whatever measured force is necessary to break it up. Be careful: breaking up dogfights can be dangerous. Consider your own safety first. In most cases, injuries sustained by intervening owners are far worse than the dogs suffer. Avoid reacting hysterically and screaming at the dogs and the other people. Do not insert a hand or foot between the two rival dogs because their natural reaction may be to redirect the attack to you. But you should know that ultimately you are responsible for your dog's actions.
