My breeder had Josie on a 5 way shot. at 8 weeks old She had her updated 5 way shot last week at 12 weeks. In about 4 weeks she's going back into the vets again to get another shot. Then it goes on from there. She should be dewormed up until 11 weeks old then you can start putting her on heart worm preventative at 12 weeks.
She will not get her rabies until she hits 5 months old because i don't want to overwhelm her system. I hear vets who give puppies shots usually use the same amount of dosage for adult dogs which can be dangerous.That's why Josie does not get vaccinated for everything all at once. I made sure my vet spread it out and he agreed to it fortunately.
talk to your vet about it he should know what needs to be done and you can decide from there if it sounds right. Let them know about your concern for over vaccinating and they should be able to work with you from there. Depends on the vet too i think every vet works alittle different.
