Dogs that have not been vaccinated cannot be taken out because the body has not produced antibodies to resist viruses in the external environment. Common canine severe infectious diseases include parvovirus, canine distemper, canine corona, etc. Puppies are more susceptible, and unvaccinated adult dogs can also be infected. Vaccination is the safest way. Antibodies should also be tested after the first year of immunization is completed. Check whether the antibody titer reaches the standard. If the antibody titer is not up to standard, you should receive additional vaccinations. After the antibody titer is up to standard, you can strengthen the vaccination every year.

What to pay attention to when vaccinating dogs:

1. Do not let your dog get vaccinated on an empty stomach. It is recommended to give the dog something to eat before taking it to the hospital for vaccination. Vaccination on an empty stomach will cause hypoglycemia in the dog, but it is not recommended to eat too much, as it may also cause vomiting. Just eat some in moderation. it is okay.

2. When injecting dogs with vaccinations, you must choose regular drugs. At the same time, vaccinations must be carried out under the advice of veterinarians. Only injecting dogs regularly according to the efficacy of the medicine is effective.

3. Vaccine injections need to have a certain continuity. If you are sure to vaccinate your dog, annual injections are necessary, and generally speaking, the vaccine for the next year should be given half a month to a month earlier than the previous year's injection to avoid accidents when the vaccine is about to expire.
