what age are dogs supposed to get shots
July 4, 2009. Puppies are irresistible but vulnerable. They depend on you to replace that vulnerability with a vaccination shield. Your puppy should get his first shots between 5 to 7 weeks old, concluding with a few more rounds by 16 weeks old. Your veterinarian should assess your pup's health prior to getting vaccinated, as illness can interfere with a vaccine's ability to work.
