You've had some excellent advice so far. You could also read the 'Book of the Bitch' as a good foundation for your search for knowledge. You should discuss your plans with your dog's breeder to see what she says and get her advice on breeding. Visit the shows. Show your dog. Talk to people who have dogs at stud (it's not studding your dog so I wouldn't use that phrase or you'll just get told to go away!). There is such a lot you need to know. Are you prepared to help pups sired by your dog a home? Will you offer advice to new owners? They do approach the dog's owner as well as the bitches. Importantly and already mentioned - why should bitches come to your dog? What can you offer them? Will you show him and do well? If not, why would they come to you?

Have to be honest that it does sound like you've bought a dog and just want to make money out of him which isn't what breeding should be about. You should have a desire to improve your breed, to produce high quality pups (rather than lots of poor quality pups), you should be choosy over which bitches so that they complement your dog's lines - do you know enough about lineage to do this? Do you know about every dog in his pedigree, what their faults are, what their qualities are, what their temperament was like? Do you know enough about other lines to know the answers to these questions so you can make good choices? I suspect not, so the first thing to do before you consider using your dog is to find out as much about your breed and the lines in it as possible - meet the dogs that are still around, get to know owners and talk dogs, dogs and more dogs. Be willing to learn from them.

Your dog is a pet, not to be seen as a money maker, enjoy him and do your research.
