I do rabies and DAPP every three years, and will continue to do so until age/health dictates otherwise. Jack and Missy's are staggered (they both got DAPP last year, they'll both get rabies this year), Heidi will be getting both this year.
Sassy was due for rabies and distemper last year, but was in poor health at the time so I declined both. I don't know what I'm going to do going forward, she's pretty old.
I don't plan on any puppies anytime soon (or ever!) but I would do DAPP at 8, 12, and (maybe?) 16 weeks, rabies at 20 weeks. Both rabies and DAPP at one year, and then every three years after that.
