Hi Serena,
Vets differ in when they give the pups their jabs - mine will only do the first at 10 weeks and the second at 12 weeks, because if there are still maternal antibodies in the bloodstream the "proper" vaccination won't 'take' properly. Then the pup can go on the ground where other dogs have been 10 days to 2 weeks later.
Can you take him in the car to places where you can sit on a bench with him on your lap to watch the world go by? This would be better than him not going out at all, and pups can get very heavy by 12 weeks!!
Good luck. :)
