My new puppy is amazing, my German shepherd loves having a little buddy to play with. 
Have you found a good vet to take care of the puppy? It's important that you do.
Yes I have that is one of the most important things to consider when having any pet. 
Good. You should ask what food what be best for your new puppy as well as feeding tips. They can offer more than just check ups and vaccines. 
Yes my vets are very good at recommending the correct products for the type dog you have.
It's good that your german shepard is getting along with the puppy. At times, one dog will try to maintain dominance over the other.
Yes that is true, my German shepherd is a very loving dog and just takes everything in her stride. 
That's great to hear! German shepherds are very intelligent and loving animals. They are super smart too. I bet it's a joy to own one.
They are great dogs especially for family’s, they are playful, smart, protective and super loving.
You have two great dogs for families then. Golden Retrievers are very playful and family friendly as well. I think you made a great choice.
