Puppies should not be allowed out of the house until they are about 4 months old, fully vaccinated, and regularly dewormed internally and externally. The initial immunization generally requires three routine vaccinations and one rabies vaccination, usually at 42 days of age, followed by three infectious disease vaccinations at 21-day intervals and a final rabies vaccination at 7-day intervals. Rabies vaccine can only be given when the dog is at least 3 months old, and then the antibody test is done 15 days after the third vaccination, and the dog can go out after passing the antibody test, which takes a total of 99 days, which means the puppy needs at least 99 days to go out.
