Puppies will also have been vet checked and will have been wormed at 2, 4, 6 and 8 weeks. 
You will also receive a lifetime of advice.

When you arrive home with your puppy, remember - your puppy is a baby Bulldog. Like all babies, he needs lots of love and cuddling, lots of rest and sleep, lots of love and cuddling, lots of good, nourishing food and more love and cuddling.
  
Moving to a new home, leaving his dam and litter mates and the only humans he has ever really known is a very traumatic experience for the puppy, so try to make the move as easy as possible for him. For the first couple of weeks, try to change his life as little as possible.
Follow the breeders feeding routine. The same times, the same amount, the same brand of food, the same supplements. Feed him in the same place at each meal. 
Be sure he has a special area all his own for his bed. Give him lots and lots of cuddling and petting. Do not let him play so long and hard that he becomes exhausted.
 
Sometime during the first week, you should take him to your veterinarian for a check up and get to know you visit. Take along the record of his immunizations and wormings and a stool sample.
 
Once the puppy is settled securely into his new home, you can begin to introduce him to your way of doing things.
If you want to change the brand of puppy food he is eating, the change should be slow and gradual. Substitute a small amount of the old food with the new brand and slowly increase the ratio of new to old until the old brand is completely replaced with the new.
