Try to introduce your fur baby to as many people, experiences, and places in his first three months. However, if he has not yet received any vaccines it is not a great idea to bring him to public places. These places could be a haven for diseases. Most of the time, dogs with illnesses or unvaccinated frequent these places. It is not worth risking the life of your dog in these parks. Wait for the approval from your vet on when you could bring your puppy to dog parks.
