Hi we are looking at getting a french bulldog puppy and have a few questions. 1. The owner is providing an AKC certification. Does that mean anything in terms of the health of the dog's parents? Did the parents have to go through health testing or does it just mean they were french bulldogs? 2. Looking at the vaccination schedule it looks like puppies are supposed to get vaccines at 8 weeks and again at 10-12 weeks. If they received the vaccine at 8 weeks are they supposed to be repeated at the 10-12 week window? If the person has not repeated the vaccinations as of 14 weeks should I be concerned?
