Seems to make more sense to let the maternal antibodies do their job and Titre them at 16 weeks and THEN if needed, vaccinate... OR... wait until 18 weeks and give initial DAPP and titre in 12 months. BUT I mean less money to be made this way...

that is ridiculous - instead of immunizing 3 times and not knowing each time and putting the puppy at risk - titer before deciding on vaccination
