People are drawn to specific breeds of dogs for various different reasons. The way they look, their temperament, the activities they excel at and you can enjoy with them. It is breeders who preserve these traits. A purposefully bred dog is one who has generations - which could mean hundreds of years - of careful selection for specific attributes. Purposeful responsible breeders aren't just churning out pups to have litters, they are selecting representatives of the breed that they feel will be honoring and preserving the breed and its function.
