Hi Dabrain,
Never buy a puppy from someone who wants to meet you somewhere. They are usually scammers or puppy farmers. Always research the breed you want and look for a good breeder. The kennel club have a list of breeders. Always make sure you ask plenty of questions about the parents and the pup. Never buy a puppy without seeing at least the mother, both parents if possible. If you don't feel happy with the puppy, mother, breeder etc then walk away. And never buy from a pet store as they are almost certain to be from puppy farms. Hope I have been of some help. Good luck with your search for your new puppy.
