Dog vaccines are usually injected once every four weeks in the first year. After the first year of injection, one injection per year is enough. If parents feel that annual injections are too frequent, they can check the antibody level every year. If If the antibody level is up to standard, there is no need for a booster shot; otherwise, a booster shot is required.
Tips:
Parents should not take the dog into unfamiliar environments before the vaccine is fully injected, and do not do anything to reduce the dog's resistance.
