Thank you for your response! Although very useful information, I was looking more along the lines of how to correct this problem and provide positive leadership to help Nala break this habit before it escalates. Sadly, you are right about staying away from the dog park but I don’t find that to be sufficient. She is still young and continued socialization is crucial whether or not it is at a dog park I still need to be able to trust her around all other dogs. Hopefully someone has some traing techniques that can help. There must be more I can do than simply removing her from the situation.
