What happens if you miss booster vaccines for a puppy?

You risked your puppy's life through ignorance. You should have taken the puppy to the vet for a check-up within 72 hours of purchase, to ensure that it had no major problems, and to set up appointments for the puppy shots. Fortunately ,you and the dog were lucky. Sadly, you supported Puppy mills by buying a puppy mill bred dog at a pet store.
