Necessary Vaccinations

[FionaBeth]

After doing research and talking to others, I have realized that not all yearly "recommended" vaccinations are necessary, or even healthy. I have and will continue to do research on this- however, I know that many members of this forum are very well informed about all things dogs, and would like to have your opinions as well.
I have had Zeus for almost a year, so it is almost time for the annual checkup. I got him from the SPCA, so he came vaccinated for distemper, parainfluenza, adenovirus, parvovirus, leptospirosis, bordetella, coronavirus and rabies. The vet has recommended that he have all of these vaccinations annually except for the coronavirus. Obviously I will get the rabies vaccination (it is required in order to license and I live in the city). I am not worried about the cost, I just do not want to have my dog unnecessarily vaccinated. I would appreciate any feedback
