Do you know who the breeder was so you can let them know the pup is now with you.
Hopefully her hearing isn't affected and she hasn't been badly scarred psychologically from the the treatment in her first home.
If you have no vaccination history then you will need to start from scratch before you take her out and about to be socialised, get her used to a lead in the house and then in the garden before venturing farther afield as she will be too big to carry.
I hope she settles in well with you.
