Here is a typical description on buying puppies. This comes from a site I'm currently reading on BCs, but is applicable to all breeds;

"Where should I get my dog?

There are several options, some good, others not so good. If you choose to get an adult dog, you can get one from a shelter, from a Border Collie rescue organization, or from a breeder who is looking for a home for an adult Border Collie. If you decide to get a puppy, you should do some research and find a breeder with a good reputation. Do not buy a Border Collie puppy from a pet store. Although these puppies are adorable, they are generally from puppy mills and are incredibly overpriced. Most people don't realize that they can usually buy a very well-bred, well-socialized, pet-quality puppy with exceptional guarantees from a reputable breeder for less money than they can buy a puppy from a pet store. Pet store puppies have usually been bred for profit with little consideration given to long-term health. They are often prone to many problems, such as epilepsy, hip and joint problems, and early blindness. They are also usually poorly socialized, which means they can grow up to be timid, fearful dogs. Do not even buy from pet stores advertising that their animals are not from puppy mills: no reputable breeder would ever sell puppies to a pet store! You will often encounter the same problems with health and socialization with puppies sold through ads in the newspaper. The best way to find a good breeder is by asking people who already own healthy Border Collies with good temperaments."
