How old can a dog be for vaccination

Generally after we buy a puppy, usually about two months, we recommend that the words are generally raised at home for 10 to 15 days, if everything is normal, then we should immediately take to the vet for vaccination, this vaccine we can choose multiple vaccines, such as Weijia five, or Weijia eight, or Intervet’s four or six. After the vaccination, we recommend checking the antibodies after 20 days, as the main purpose of the antibodies is to see if the vaccine has had any effect. If the antibody titer is not good, then we will need to give one or two additional vaccinations depending on the antibodies, so that the vaccine can have sufficient effect to protect the dog.
