My adult dogs have not been vaccinated for several years except for their rabies as required by law.
Puppy vaccines and one year booster are a must. One of my H litter's owners was concerned about vaccines and ended up with treating her dog (had insurance) with bills mounting to over $10K - the dog was definitively diagonsed with distemper, and at a little over 2 years old was humanely put to sleep when the seizures and neurological deficiencies could not be controlled.
Do not skip puppy vaccines or first round of boosters.
