Is your dog an outstanding specimen of his breed? Responsible breeders, those who strive to improve and preserve the desired points of their breed as listed in the breed standard, are looking to use dogs to enhance the qualities of their bitches.
The dog would have to prove himself in the showring, be of excellent temperament, and undergo the relevant health tests applicable to the breed.
Sadly there are too many puppies, no matter how sweet and loveable, who are the product of ignorance and greed.
Breeding should be carried out with a purpose in mind, not only to provide companions for the puppy buyer (this can be provided by any little dog), this purpose should be to Preserve and possibly Improve the breed, by eliminating health problems (thankfully dogs have far fewer hereditary problems than people), to mate together animals with these aims in mind requires a lot of study of the pairs ancestors good and bad points, are you in a position to know anything of your dogs ancestors, other than their names, and whether they were Champions or not?
Enjoy your pet, and when you come to want another go to a breeder who has carefully considered all the above points!
