Only if you want to avoid quarrantine briedog, you can bring in puppies from 12 weeks and probably earlier but they would have to spend 6 months in quarrantine.
As I understand it, a pregnant bitch can come into a quarantine kennel, have the puppies and when no longer needed by the puppies, return home. The puppies, having been born in this country can come straight out of quarantine without having to spend any more time in there.
