Update:

So, I wrote to the breeder and she agreed that it wasn't the most optimal timing for us to get a puppy right now. BUT the great news is that she is planning to take a litter next spring with her own female and the same male! So we will go and see her and the dogs as soon as Alex is home again. So that the breeder gets a chance to meet us and we a chance to meet the mother and the puppies. But from what she read about Alex and me she said that she definitely wanted to keep contact with us. Let's hope for the best! And that we are ready next year for a little baby :)
