If you do let her get beat up by aggressive dogs, you can cause her to become dog reactive.
I do not understand the desire for people to have their dogs run about with other people's dogs. Isn't it hard enough to be responsible for your own dog's body language, needs, etc. Watching other people's dogs interact with yours -- isn't that always a question.
And if your dog is fearful now at 12 months, at 15 months or at 18 months, she may turn around and lay into one of these dogs ripping them open. Will this make a difference in how you feel about her?
