The lifespan of a Teddy has nothing to do with whether it has been vaccinated. If the dog is in poor health and has not been vaccinated, it is very susceptible to diseases, resulting in a greatly shortened lifespan. Therefore, for the safety of your family and the dog, it is best to Inject the vaccine on time, and do not bathe the dog before and after vaccination, so as not to affect the efficacy of the medicine and prevent the formation of immunity. During this period, strengthen nutritional supplements, which is beneficial to the dog's health.
