How old is Sadie? I don't agree with once a year vaccines at all. However, if she just turned 1 year old, then she will need another booster. I like Dr. Jean Dodds protocol.
Puppy shots are usually at approx. 8 weeks, 12 weeks and 15-16 weeks (DHPP) and then rabies whenever required by law in your state. Then, at one year old, you do one booster (one shot) of DHPP, and then again rabies. My vet told me both these vaccines are good for the next 3yrs, however, I don't know if I will be getting Jackson anymore DHPP for the rest of his life unless absolutely necessary. Rabies is obviously required legally. I guess in 3yrs, I will decide if he gets another DHPP.
