Does my 13-month dog need to restart shots if last was at 4 months?

Updated on September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Male | unneutered | 1 year and 1 month old | 6.5 lbs

I only gave my dog his 2nd set of puppy shots. This was when he was about 4 months. He is now 13 months. Does he have to start his vaccinations from the beginning?

No, Royal does not need to start his vaccines from the beginning. Because he got his second round when he was four months old, his immune system was developed enough and he will have low maternal antibodies that will enable protect. Dogs do need a booster shot one year after the first, and Royal should therefore get another booster of the vaccines by the time he is 16 months old.
