I believe everyone knows that if you have a dog or cat, you need to vaccinate them. This is not only for their health, but also to reassure us. But many people are not sure how old dogs can be vaccinated? What types of vaccines are there? Today, the editor will tell you about dog vaccines.

How old can a dog be vaccinated?

　Dogs carry some antibodies from their mothers when they are born, so their bodies are not easily infected with viruses and bacteria at this time, so they do not need to be vaccinated.

Generally speaking, the antibodies brought by the dog from the mother slowly disappear around the 45th day of life, so dogs need to be vaccinated for protection. Generally, the first vaccination starts at 45 days, and then every 4 Give the second shot at about 6 weeks, so three shots are needed in a row. Then the vaccine for the dog's childhood is complete. After the dog reaches adulthood, it only needs to be shot once a year to achieve a good preventive effect. .
