I've shared that very protocol of natural exposure on this post, Olivia. Vets can push "ideas" all they want (and will, quite often). It's up to you to decide what you want to do. And yes: highly recommend a titer test. You don't mention how old your pup is, but if over 9 mo. of age, with all the exposure she's likely had, you likely won't need nosodes.
Finally, homeopathic vets need not be near you to help you. See this post for those who do mostly/only homeopathy and consult by phone.
