My pups go out even before they're jabs, in the car, in my arms and around dogs that you know have been vaccinated, imo a disease is easier to cure in a pup than a lifetime behavouiral problem as you maywell end up with, vets these days seem to be over reacting with injections, mine get done at 8 weeks old a week after that i start takeing them out everywhere and anywhere, they get there second one at 12 weeks old and i carry on with what i started at 9 weeks old, i have never had a pup catch a disease and never had an anti social dog.
