congratulations on your new dog! I wouldn't worry about a name change. They are very smart and she will get it soon enough. I got my Billy at 3 1/2 months old and he was very attached to his breeder. It took him a couple of weeks to adjust to his new home and then he bonded to me easily after that. They just love to be loved and since you have plenty of that to give to her, she should bond with you without trouble.
