This is a tough situation. Its hard to re-socialise an older dog. What age is she?
Are there any dog trainers close by you that could maybe help you work on it.
If you had a friend to help, you could try desensitize her. Walk another dog a good distance away and get her attention giving her treats etc. Slowly over a few days/weeks get them to bring the dog closer and closer (I emphasise slowly) - until the point that you can keep her attention when the dog is just a couple of meters away. Repitition and patience is what this calls for. You will need some high value treats like chicken/sausage/frankfurters. It might work and I have known dogs that this has worked with before but again a dog trainer would be a lot more experienced at this.
