Don't vaccinate dogs until they are one or six weeks old.
At this time, the immune system of puppies is strictly protected by maternal antibodies in colostrum. Even if vaccinated, the vaccine will be neutralized by colostrum and cannot stimulate the immune system. Therefore, when dogs are obviously in the protective period of colostrum, they should not and do not need to be vaccinated. There is often no uniform time for the maternal antibody to subside, because the bitches themselves have different qualities, so the core vaccine is generally injected with three injections, in order to avoid the action period of the maternal antibody as much as possible.
Second, don't vaccinate dogs when their health status is unknown.
Before vaccination, you must have a basic check-up on your dog's health. If the dog has been infected with some viruses before vaccination, it enters the incubation period without showing the characteristics of the disease, and at this time the dog's immune system is running at a high intensity. If you vaccinate at this time, the virus that was in a latent state before is more likely to cause infection and become a good opportunity for virus attacks.
Third, don't vaccinate dogs until insect repellent is finished.
Intestinal parasites may also be the cause of vaccine failure. Intestinal parasites are very common in puppies, and puppies may be infected by bitches before or after birth. The existence of parasites inside and outside the body has always been considered as a complex stress state, and some parasitic infections may lead to immunosuppression. Therefore, the new dog should be observed 1 to 2 weeks after arriving home to make sure there are no symptoms of the disease. Two days before the vaccination, dogs should be treated with Fulaien spray to repel parasites in vivo and in vitro, and at the same time, dogs should be treated with heart-protecting beef slices to repel parasites in vivo and in vitro. Do a good job of deworming first, and then vaccinate, so as to ensure the effect of the vaccine.
4. Don't vaccinate the puppy when it is nervous.
Stress will increase the secretion of adrenaline, which will reduce immunity. Moreover, frequent switching between different environments will make the puppy very nervous and even afraid, which is often ignored by the owner. Puppies under 8 weeks are not recommended.
Beauty hospital or pet hospital, which will not only increase its tension, but also easily expose it to pathogens. It is suggested that the puppy should adapt to the new home at least 1 to 2 weeks. When it adapts to the new environment and confirms that everything is healthy, it should be vaccinated, so that the vaccine has the best effect. Within one week of vaccination, you should avoid emergencies, such as taking a bath, exchanging dog food, being scared, etc.
