Congratulations on your new addition but remember this is just a baby.
You need to let her adjust to you and her new surroundings and slowly change her food by mingling what the breeder fed her to what you want to change her to. What did the breeder feed her?
I would not take her to the groomer yet ...if she smells you could give her a bath at home but the groomer can be scary and she needs to settle in first. This is the time she learns to trust you.
Take your time and enjoy her.
