Dogs should receive the first round of vaccines for distemper, parvovirus and canine hepatitis when they reach 6 weeks old, states WebMD. The rabies vaccine should be given as soon as possible, when the dog reaches 12 weeks old. These are the core vaccines for every dog.
The distemper, parvovirus and canine hepatitis vaccines require three rounds between 6 and 16 weeks old, states WebMD. The rabies vaccine requires only one round. There are two types of rabies vaccines available: a one-year vaccine and a three-year vaccine.
Veterinarians may recommend other vaccines, such as the bordatella or Lyme disease vaccines, based on the dog's location and risk factors. The schedule for non-core vaccines varies depending on the vaccine type and the veterinarian's recommendation, explains WebMD.
