Puppies are weaned for about one week and must start regular vaccination. When the young dogs get vaccinated for the first time, they will have to be vaccinated once a month for the next two months.

Under general rules, after vaccination, the body receives stimulation from the antigenic substance - the vaccine. The antibody takes a certain amount of time to produce it, which takes about 2-3 weeks. However, the antibodies produced for the first time not only last for a short time, but also have very few quantity. A small amount of antibodies does not have any effect on infectious diseases and cannot play an epidemic prevention role, so it is not possible to take a vaccine once.

is subjected to the second inoculation, and a large amount of antibodies in the body can be quickly produced, dozens of times the first reaction, and stay in the body for a longer time. If the third dose is given 3-4 weeks after the second dose, the number of antibodies produced by the body will increase by dozens of times on the basis of the second dose. This makes the dog's body capable of resisting infectious diseases, and the remaining time in the body can last for up to one year.
