While there are many places a purebred puppy can be purchased, only one source can be recommended with confidence -- a responsible, reputable breeder. While places like pet shops are motivated by profit and quick turn-over, there dogs also often come from puppy mills, less that choice living conditions, mass produced, and have health problems or can be sick, to name a few problems, not to even mention the usual low quality or badly breed dogs they send out. A reputable breeder only produces puppies because of a love of the breed and a dream of perfection. To that end, responsible breeders carefully screen breeding pairs, check out health issues, compliment a pedigree, work to improve faults, and breed to strengthen or enhance a line, provide the buyer with a written guarantee, and provide support and advice to the new owners throughout the dog's life. Reputable breeders are usually a member of the national breed club, but not always, and being a member of that club or selling AKC dogs in itself is no guarantee of quality or an ethical breeder alone. Some people use those memberships as a tool when talking with a less than informed buyer. It is a good thing by all means, and you should look for that, but there is plenty other things which must come along with it. A reputable breeder strives to produce beautiful dogs according to the standard of perfection for the breed, they also place equal importance in breeding dogs that have good temperaments, are sound, and are healthy.
A reputable breeder is constantly striving to produce better dogs with each generation, and their selection of dogs used for breeding is a result of years of study and a thorough knowledge of the breed. Because this type of breeder is trying to produce puppies that they can win with in the show ring, they are highly motivated to do the best breeding possible. Any puppy sold should be a pet first, a loved family member. However, not every puppy produced will meet the exceptionally high standards demanded of a top show dog. The puppies who for one reason or another are not destined for the conformation ring will then be offered for sale as companions to deserving homes.
