Puppies are able to socialize with other dogs and go for walks seven days after their last major vaccination, which is administered at 12 weeks of age. Consult a veterinarian when in doubt about the proper vaccination protocol for a pet.
Most puppies receive a five-way combination vaccine at six, nine and 12 weeks of age, with a booster at 15 weeks of age. However, veterinarians sometimes recommend a special vaccination at five weeks for puppies thought to be at high risk for contracting the parvovirus, according to PetEducation.com. Puppies also require a rabies vaccine at 12 weeks. To maintain continuous protection, adult dogs require an annual canine cough booster and a tri-annual vaccine booster.
