If one puppy from a litter of eleven puppies does not receive it's first puppy vaccination at the same time as his siblings, will this one puppy be at great risk of contracting disease from it's vaccinated siblings. The puppies are being vaccinated at almost 8 weeks old and the unvaccinated puppy would be with his vaccinated siblings for 2 days before going to his new home?

Hello and welcome to Petco Pet Education Center, formerly Petcoach. The unvaccinated Puppy will be at risk of contracting viruses from the environment that the litter-mates will be protected from, not at risk of getting the virus from the other puppies. If the environment is clean and free from viruses, and no exposure to unvaccinated animals occurs, then Junior should be ok. I recommend getting him vaccinated ASAP. At 8 weeks though he should still have some immunity from his mom if she was vaccinated. Best of luck with Junior!
