If you end up buying a puppy that is poorly bred, you may find yourself encountering genetic problems in the future. A reputable breeder or pet store gives importance to their puppies. If you are buying from a breeder, he or she will ask about your lifestyle, along with your future plans for the puppy. Reputable breeders often have long waiting lines, which is one of the signs you should be looking out for. Reliable and trustworthy breeders will also be able to provide you with a genetic guarantee for your puppy, and many are registered with the AKC.
