When should the first dose of vaccine be given to dogs?

The first dose of immunization: that is, giving the dog the first dose of vaccine. This needs to be done to ensure that the dog is at least 6 weeks old and in good health.

Start vaccinating 4 or 6 vaccines directly at 6 weeks of age. There are three shots in total, with an interval of 3 weeks between each shot. The rabies vaccine can be given at the same time as the third vaccination, or it can be given one week later. After one year of age, It is sufficient to receive a 4-way or 6-way vaccine and rabies vaccine once a year.

Parents can generally judge a dog's physical health simply from three aspects: active spirit, strong appetite, and normal bowel movements. At this time, if the dog happens to be over age, it can be taken to the pet hospital to be vaccinated by veterinarians. There will also be a special vaccine book to record the dog's immunity status.

Why can’t dogs be vaccinated if they are not healthy?

This is because most of the vaccines on the market are attenuated vaccines, and taking this kind of vaccine is an external invasion and can lead to infection, so the dog’s resistance is needed to resist it. If the resistance is not good, it will A series of rejection reactions will occur. Therefore, injecting vaccines when the dog is unhealthy may have the opposite effect, so it is best not to vaccinate the dog when it is unhealthy.

Note: The dog’s physical condition will decline after the first dose of vaccine. Do not bathe the dog or take it out to prevent illness or infectious diseases.

How to give the second shot of immunity

The second shot of immunity: that is, giving the dog the second shot of immunity. The vaccination is given 21 days after the first dose and must be done under the premise of ensuring good health.

At this time, what needs to be paid attention to is internal and external deworming and environmental care. The correct method of deworming is to do the first internal deworming when the puppy is 2 weeks old, and the second internal deworming when the puppy is one month old. When the puppy is 2 months old, it can be dewormed internally and externally. The amount of internal deworming medication needs to be strictly based on the weight at that time. , it is recommended to do it under the guidance of a veterinarian.

Environmental care requires keeping the temperature of the dog's resting place at a constant temperature. Since the temperature tolerance is different depending on the breed, there is generally no problem as long as the dog does not shiver while sleeping. It should be noted that do not let it lie on the floor for a long time. This is because the dog's belly has sparse hair and is very susceptible to cold, which can cause gastrointestinal diseases and infectious diseases. This must not be ignored.

In addition, the external environment is complex, so it is best not to let the dog go out during the vaccination period to avoid contracting the disease. As long as parents keep their dog's resting place dry and tidy and prevent it from being exposed to humid conditions, it will generally survive the second stage healthily.

Is the third dose of dog vaccine important?

Puppies need to receive three doses of vaccine because they need to repeatedly stimulate memory lymphocytes, which is determined by biological immunology.

Most of the attenuated virus of the first shot of the vaccine is combined with maternal antibodies and swallowed up. Even if antibodies are produced, only a small amount can be produced.Antibody levels and short duration. Specific immune responses can only produce more antibodies and maintain longer-term effects under multiple stimulations at reasonable intervals.

To be specific, puppies are stimulated by antigenic substances - vaccines, and it takes 2-3 weeks to produce a large number of antibodies. However, the number of antibodies produced for the first time is very small, and the duration of maintenance is also short. There is also the combination of maternal antibodies. The remaining antibodies are ineffective against infectious diseases and cannot play a preventive role, so the first shot is quite As cannon fodder.

After the initial vaccination, the second vaccination is given 2-3 weeks apart. At this time, the puppy's B cells proliferate and differentiate into memory cells and plasma cells, which will quickly produce corresponding antibodies. When the third shot is given at the end, the immune strength and immunity time can last for a longer period of time, so generally the initial immunization requires three times.
