I am only stating what we have found, if we were to go to our vet and get them jabs at 8 weeks and the pup went home to get the second jab 2 weeks latter. Some and i do stress some vets might not work with the jab that my local vet had used. Also from vast experience vets have differing ideas at when a pup should get a jab as i stated some will not and refuse to give a jag to a pup till weeks 10/12. Most vets will not jab a pup at 6 weeks. As you know by then the pup will be with the new owners. The most important period for a pup learning is around 10/16 weeks. this is best done away from the mother.
I thought that the issue was about pup's getting PV with a breeder, this matter is only personal choice with individual breeders, a pup will not contact any infection if they are cared for properly as we do. Advice is given to all new owners what to do when they get the pup home. We vet all possible new owners, and are rejected if they do not come over as responsible people. It is not the first time we have had to refuse a pup to an inquiring member.
Anyway the Kennel Club will not recognize the Labradoodle breed. Also they are responsible for causing a lot of harm with certain breeds due to looking for the perfect shape, size head coat and so on. They have a lot to answer for.
