I’ve read the links and they say one is sufficient once the mother’s antibodies no long interfere. since we do know exactly when the mothers anitbodies are going to dissapear what are your views on just vaccinating once after 16 weeks?

Also, what if you get a dog at an older age and you do not know if the dog has had any vaccinations how many rounds of vaccines do they need? I know the links say one is good, but what are your views on this?

If you start at 16 weeks or after, I personally would do 2.
