I think if your girls love her, that is reason enough to ask if you can keep her. Just tell your neighbor that the girls have grown attached to her and were wondering if he would entertain the idea of you guys keeping her. If he says no, then you could maybe ask if you could buy her. He obviously has no emotional attachment to her or he'd never have let you guys have her for as long as you have. But I suspect he'll want a good dollar for her - especially if he's bred her in the past.
