Under normal circumstances, the dog's rabies vaccine needs to be vaccinated for the first time after the dog reaches three months of age, and then a booster shot is given once a year.

This is because it takes nearly half a month for dogs to produce sufficient antibodies in their bodies after being vaccinated against rabies. , immunity can reach its peak, so the rabies vaccine is injected one month in advance every year, so that the immunity to rabies can be seamlessly connected, and there is no window period to protect dogs throughout the year.
