Ours all had their first vaccination at 8 weeks and second at 10 weeks. Suki was a rescue, so she had already had her first one and when we collected her at 10 weeks, we took her for her second jab the next day. As we had other dogs, we figured that as they were being walked regularly, Suki was being bombarded with any germs they may bring home, so only waited a week before taking her out (the vet had advised 10 days - 2 weeks) but she was so terrified of the whole world, we still ended up carrying her a lot for the first week or so.
I agree with the others and would call your breeder and get the vets to talk to each other - if they will!
Good luck and happy walkies when you can finally go.
