I agree with Debles, and a lot of other advice already given.
Here's my two cents (for what it's worth).
First of all, relax and don't worry. Your dog will love you. Goldens are highly social and love people. I mean they really, really, love people. They NEED people very much.
Your puppy is a highly social being, and she is also still a baby. The only life she's known so far is being with her litter and her Mom. She was very bonded to them, and loved them very much. Then, one day, they were gone, and she's with new people (you). This might be scary for her. Winnie was very, very upset when he came home with us and left his litter. He's 8 and 1/2 now, and absolutely loves and adores us. I'm his most important person, my husband is his best buddy and most fun playmate, and my daughter is HIS baby who he'd defend to the end, if he had to. He loves her simply because she is an extension of me. And because she tends to drop food on the floor. And Winnie loves food.
But, my big huge lovable oaf has separation anxiety to this day. Leaving his littermates was so upsetting to him, that he still doesn't like to be alone. I think he worries we're not coming back. And he loves us so much.
So give your baby some time. She will learn that she has a new family now. And you will be her entire world, and she will give you more love than you ever expected. At least, this is what Winnie did with me.
Winnie is not a lap cuddler, he's too big. But he loves to be NEAR me. No matter what. This means I never take a shower or go to the restroom alone. Ever. And he's never more than a few feet away from me.
And as much as he loves me, and he does, he also loves everyone else, too. Not as much. But Winnie never met a stranger. He only meets new friends. I thought for years that Winnie had this "I love you" expression, just for me, when he wrinkles up his big brown eyes and makes them so soft and loving, and his mouth turns into a soft, lazy smile. I called this Winnie's "I love you" face. Well, we moved from VA to TX last year, and the first thing Winnie did at our new Vet's office was give his 'I love you face' (special and just for me!) to all of the female Vet-techs at the office. The little flirt!
But I love him and his personality, so for a few minutes I was upset and jealous, and then I realized this is just what makes Winnie be Winnie, and it's why I love him. So my boy is a flirt. Worse things could happen, right?
Your baby girl will grow into herself, her personality, and your family with time. She is just a baby, and is now learning about her new life, and you, and her new pack. Give her time, with love and patience, she'll figure it out. I promise!
