Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 1 month and 22 days old

Is it okay for my puppy to still be around his brothers and sisters if he's the only one out of all of them that has his first set of shots?

As long as the other puppies are not in contact with other dogs and they live all together, that might be fine, aka, if none of them are exposed to possible puppy viruses. That said, if the puppies do not live all together anymore, then I would advise he does not see them anymore until they are properly vaccinated, sadly littermates that are separated and expose two different environments are not safe went back together if not properly vaccinated. You had a great question , I truly enjoyed answering it and hope you will use Petco Pet Education Center, formerly Petcoach in the near future. PS puppies must be vaccinated every 2 to 4 weeks until they are four months of age, this starting as early as 6 to 8 weeks and in some cases, in a shelter environment, as early as 4 to 5 weeks of age.
