Dog vaccines

At present, the common injection frequency is once a year. In addition to the first injection that requires three times and a total of four injections, the spider needs one injection every year for the subsequent consolidation injection. It is generally believed that the immunity of core vaccines lasts relatively long, while the immunity of non-core vaccines lasts relatively short. Some foreign veterinarians have begun to recommend that core vaccines be injected every three years. Pet owners can determine whether continued consolidation injections are needed by testing their dogs’ antibodies in the hospital.
