If parvo is a concern, just do parvo 1st & wait until she's 9-10 weeks old to do everything else. But I'm not sure if most vets just have the parvo shot? Most vaccines are a combo deal...don't think they just have distemper + parvo either.
From Dr. Dodds blog:
Dr. Jean Dodds' Pet Health Resource Blog | 2013 and 2014 Canine Vaccination Protocol - W. Jean Dodds, DVM
Hi Stephanie, I have heard Dr. Dodds say you can vaccinate at 6 weeks for Parvo alone and then follow the regular 9 and 14 week protocol with DPV. Of course, it all depends on the situation. The dosage amount for CPV depends on the breed. Please let me know and I will forward this to her. Thanks, Admin
