I'm very minimal when it comes to vaccines. However, I believe that puppy vaccines are VERY important and not to be skipped.
Pup should have shots at 8 weeks, 12 weeks, 16 weeks (or something very similar) and rabies by whenever the law states (each state is different). Then at one year old, get the DHP boosted and rabies. Thereafter, you can kind of choose. I am opting not to get my boy any more vaccines for the rest of his life (besides rabies every 3 yrs as per the law). He's now 5.
Bordatella is one of those that is questionable. Many places require it (boarding, daycare, groomers, etc) so... it's hard to get out of in those situations. I wouldn't say it's one of the more 'harmful' vaccines, but I won't be getting it anymore after bad experiences, but we also don't do boarding, daycare and our groomer does not require it (mobile). So hopefully it doesn't become a big issue.
