Dogs need to be checked before vaccination

Generally speaking, vaccination is not dangerous to dogs, but if vaccinated in a diseased state, it will be life-threatening. Therefore, be sure to ask a veterinarian to check the dog's body before injecting it.
(1) For dogs with poor physical fitness and malnutrition, it is best to improve their physical fitness and strengthen nutrition first, and then vaccinate them until they are healthy.
(2) Vaccination cannot be given when the disease occurs. If vaccinated at this time, the vaccine reaction will aggravate the condition and may prevent the vaccine from producing an immune effect.
(3) If you have been in contact with a sick dog before injection, you need to undergo a comprehensive examination before injecting the vaccine. If your dog has the following symptoms, it means that he is not feeling well, so don’t rush to get vaccinated yet:
①Fever.
②Cough.
③Diarrhea.
④ Increased eye mucus.
⑤Dry nose.
⑥Vomiting.

The effects, prices and brands of dog vaccinations

1. Get Vaccinated
The vaccine is actually a weakened, less active version of the virus. The viruses used for vaccines are specially cultured and technically processed. Their activity is much lower than normal viruses and can help dogs develop resistance. After being vaccinated, even if you are infected with a normal virus in the future, your immunity after exercise will be enough to deal with it.
2. Which vaccine is better to choose
There are two vaccines on the market. One is domestic and the other is imported.
Although imported vaccines are more expensive, generally domestic vaccines can only guarantee the effectiveness of epidemic prevention for half a year. Not only do they need to be administered twice a year, but some vaccines will lose part of their effectiveness under high temperatures. Therefore, if economic conditions permit, it is recommended to take imported vaccines as it is safer.

Dog immunization schedule

Vaccinations must strictly follow the immunization schedule set by the doctor. Injecting the puppy too early will not only not protect the puppy’s health, but will destroy the efficacy of maternal antibodies and cause to the opposite effect.
The vaccination can be carried out according to the following time:
(1) 30 days after the dog is born - intranasal vaccination for canine cough vaccine;
(2) 7-8 weeks after the dog is born - The first six-linked vaccine injection;
(3) The dog is born at 11-12 weeks-the second six-linked vaccine injection;
(4) The dog is born between 14-15 weeks-the third Six-part vaccine and rabies vaccine.
After all is completed, as long as a six-link vaccine and a rabies vaccine are injected every year, you can take your dog out safely.
Tips:
If the dog cannot find the brand of vaccine used in the first immunization during the second immunization, you can use other brands of vaccines instead. Regardless of the size of the dog, only one dose is given for each vaccination, and the dose of the vaccine has nothing to do with body weight.
Injecting vaccines into pregnant bitches may cause miscarriage and is absolutely prohibited. When animals are pregnant, they have very high antibodies in their bodies and generally do not suffer from infectious diseases and do not need to be vaccinated. If you really need to get vaccinated, you can only use the inactivated vaccine. It is not suitable to be vaccinated within half a month after giving birth. Dogs whose injuries have not healed are also not suitable for vaccination.

Reactions of dogs after vaccination

(1) Problems such as increased body temperature, depression, loss of appetite, pain, etc. after vaccination in dogs are all Normally, it will usually be fine in about two hours.
(2) If there is itching all over the body and facial swelling, it means you have an allergy, and you should go to the hospital immediately for a desensitization injection.
(3) There are also some dogs that become ill within a few days to more than ten days after being vaccinated. This is mainly due to the following two situations: First, the dog is already sick when vaccinated, but is in the incubation period and has no clinical symptoms. It hasn't appeared yet. Second, the dog becomes infected with the virus after vaccination and before the vaccine takes effect (because the antibody reaches its peak only ten days after vaccination, and at this stage, the dog is in a state of no resistance). At this time, the onset will be very serious and you need to be sent to the hospital for treatment immediately.
(4) Remember to strictly prohibit bathing your dog within ten days after vaccination to prevent the body’s resistance from decreasing.
Tips: A few tips
Dogs that are kept at home and rarely go out still need to be vaccinated. Because the owner goes out, he may bring germs home. The temperature in spring and autumn is suitable, which helps the vaccine to work, so it is best to get the injection in spring and autumn.
