It is important to finish your pets vaccinations and most pets have to get 3 sets, depending on when the vaccinations were started and stopped. Typically vaccines are stopped between 14-16 weeks, of age, but again it depends on the sequence of vaccinations received. I would recommend that you repost with the exact vaccine dates,if given by a vet or not (breeder vaccinations should almost always be repeated b/c there is no guarantee they were done properly), and your pets actual birthdate. With this added information we can let you know for a certainty if Rosie is completely finished with her puppy rounds or if she needs additional immunizations. Thank you and take care!
