The interval between the third dose of vaccine in dogs is more than 2 1 day. Do you need a fourth dose of reinforcement?

According to the advice of general veterinarians, the third dose of vaccine for dogs is generally completed within 3 to 4 weeks after the second dose of vaccine. If the interval between the third vaccination of dogs exceeds this period, it is usually necessary to take another booster vaccine. This is because the effect of the vaccine may weaken with the extension of time, and it is necessary to strengthen the needle to improve immunity. Therefore, if the interval between the third dose of vaccine and the dog is more than 2 1 day, it is recommended to consult the veterinarian again and vaccinate the dog with the fourth dose of booster vaccine in time.
