The phrase "to breed dogs" means to intentionally mate two purebred dogs with the goal of producing puppies that inherit their parents' traits and characteristics. This process is done by carefully selecting suitable mates for each other based on their bloodlines, physical attributes, temperament, and health history in order to maintain or improve upon a particular breed's qualities. The resulting offspring are then raised and trained to become future show dogs, working dogs, pets, or any combination thereof. Breeding dogs is an important aspect of preserving purebred dog populations and ensuring that certain traits continue in the gene pool.
