Yes, thats about right. Most dogs are vaccinated first at about 6 weeks, right around 45 days, and then again at 8-9 weeks (60 days) and then finally at 12 weeks (90 days). From there you typically just need annual booster vaccinations.
Depending on what you're getting puppy vaccinated for, however, some vets prefer to vaccinate a bit earlier, and some opt to skip the 12 week shot. You can always talk to your vet about their typical puppy plans. Overall, you're right on target though!
