Puppies can go outside to socialize with other dogs when they are fully vaccinated at about 3 months old, according to Adelaide Animal Hospital. Puppies are ready to go outside to be housebroken beginning at about 4 months of age.

It is dangerous to let puppies outside where they can come in contact with other dogs until they have had all their immunizations, which occurs at about 12 weeks of age. Adelaide Animal Hospital advises owners to wait one week after the last vaccination before allowing a puppy outside. Once puppies are able to control their elimination, at about 4 months, housetraining can begin. In the beginning, puppies need to be taken out every hour until they begin to develop an elimination schedule.
