Not just socializing.. but TRAINING with that distraction is what you need. Has she been to any classes? In my opinion classes are for proofing what you already taught amidst distraction (unless you're completely new to training). I LOVE dogs that are left out in the yard and bark like crazy at my dog when I walk by. I go back and forth a dozen times working on OB commands and desensitizing my dog to the other dog.
