At present, the main canine infectious diseases that frequently occur in China include rabies, canine distemper, canine parvovirus, canine infectious hepatitis and canine parainfluenza. Its outbreak and spread are very rapid. If treatment measures are not taken immediately, it may lead to the death of sick dogs in a short period of time, or even a vicious outbreak, that is, the disease is irreversible when it is discovered. In order to fundamentally and effectively prevent and eradicate the outbreak and spread of these infectious diseases, the most effective method is to inject dog vaccines. However, the protection rate of the vaccine is not 100%, and there are many factors that affect the effectiveness of the vaccine. Therefore, you should pay attention to any problems before and after the dog vaccine is injected, and strive to use it scientifically. What are the issues that should be paid attention to when dogs are vaccinated? Precautions for dog vaccination.
1. Accurate immunity opportunities
（ 1) It is necessary to consider the effect of maternal antibodies on the immune effect of offspring. Maternal antibodies are beneficial to the early resistance of puppies, but they are the most common factor that disrupts vaccine immunity. If the opportunity is not grasped well and the injection time is too early, when the maternal antibody titer of the puppies is still very high, the maternal antibody will experience a moderate part of the vaccine antibody, causing the body to produce less antibodies. Therefore, not only will the prevention effect not be achieved, It can also easily lead to the outbreak of diseases
(2) It is not advisable to vaccinate a dog that has just been transferred to a group or just purchased immediately. Various stress factors, such as environmental incompatibility, path stress, inconsistent feeding time and food types, will reduce the resistance of dogs that have just been transferred to the group or just purchased. Injecting the vaccine at this time will not only produce poor immunity, but may even lead to the occurrence of some diseases. Therefore, dogs that have just been transferred to a group or just purchased should not be vaccinated immediately. They should first go to a reliable animal hospital to be injected with hyperimmune serum or immune globulin 2~3, and wait until the dog is suitable for the environment and diet before getting vaccinated
(3) Vaccine pregnant dogs carefully. Generally speaking, pregnant dogs cannot be vaccinated with attenuated vaccines, but inactivated vaccines can be used. The reason is that the immune response induced by attenuated vaccines is stronger and can cause damage to the fetus. Some studies have shown that canine parvovirus vaccine and canine adenovirus vaccine can cause harm to the fetus. Therefore, you should try to avoid injecting attenuated vaccines into dogs during pregnancy.
(4) Enhance immunity in a timely manner. Many dog owners believe that dogs breed! A single vaccine can protect against the disease for a lifetime, which is not the case. This is becauseFor, No.! After the first vaccination is completed, the antibody level will gradually decrease, which is no longer enough to protect the dog's safety, so a booster vaccination is necessary every year.
2. Understand the health status of the dog before breeding
(2) Nutrition: Although it is extremely common to reduce the response to rabbit plague due to insufficient nutrition, dogs' vitamin and selenium deficiencies are related to the suppression of rabbit plague. It has been reported that canine distemper outbreaks are more common in dogs due to a lack of vitamins, minerals and selenium.
(3) Parasites inside and outside the body: The existence of parasites inside and outside the body has always been considered a complex stress state. It has been recently shown that some parasites (such as Demodex folliculorum) ) is probably an immunosuppressant of straight crosses. Therefore, preventive injections can only be given after the patient recovers.
