A puppy can be taken outside as long as the puppy is confined to its own yard and is not around other animals; however, the puppy cannot go outside in public places until the it is fully vaccinated, according to the ASPCA. Most puppies begin their vaccinations at 6 or 8 weeks of age and will be fully vaccinated by 10 or 12 weeks.
Veterinarians ask that owners keep their puppies confined to the home until 7 days after the last vaccination booster, states Adelaide Animal Hospital. Puppies are given a series of three vaccinations during their early formative weeks to help protect against common and lethal diseases.
To help the puppy retain his or her natural immunities, the owner should bring the puppy back to the veterinarian at 6 months of age, at 1 year old and then every year or 3 years (depending on the vaccination) after that.
Puppies are also given a series of worming treatments to help them avoid parasites such as roundworms, tapeworms, whipworms and hookworms. These worms can cause death in some cases and can also be transmitted to humans (though they rarely cause death in humans). Puppies should be dewormed at 2, 4, 6, 8, 10, 12, 16, 20 and 24 weeks of age. Then they should be dewormed every 3 months for the rest of their life, according to Adelaide Animal Hospital.
