Hmmmmm. Well now. I expect you would breed your black male the same as you would breed a black and tan or sable.
By starting with a dog, this is a whole lot harder for you. It makes sense. A bitch goes into heat twice a year, and most people only want to breed them one time a year. So a bitch owner will travel distance, and pay good money to use the best stud dog for her bitch. She wants to use this cycle to the best advantage. So if the bitch is any quality at all, then they are not going to breed her to your dog unless you can prove him inside and out.
How do you go about doing that? Pedigree is important, definitely needs to be considered with every breeding, but it tells you only what is behind your dog, not who your dog is, and what he brings to the table. You need to build a resume for your dog. You need to have health checks, and you will want to have some titles on the dog to prove that he can be trained to a certain level. Or, if he is a working dog, list is current position and his accomplishments. A bitch owner can always find a dog owner willing to breed to the their bitch, because a dog can service many bitches in the course of a year, but a bitch owner needs more than that.
While you are building up your resume, you need to define what you want to breed for. You told us very little. The dog is black and 15 months old. What you need to define is your dog's strong points, his weak points, what you want to improve, what you hope for in the puppies, temperament, health, trainability, structure, etc. Your dog is not perfect, no dog is. You need to be able to look at your dog with a critical eye and recognize those areas where he can be better, and breed to a bitch that is correct in that area, whose sire and dam are correct in that area, etc.
I suppose the place to start is if you have a reputable breeder, that is a good place to get going. He/She will know your pup's history, and perhaps evaluate him for breeding, He may be able to give you good suggestions on who to breed to, and more importantly, who to breed away from. Ask questions about the dogs, so that you can understand why your breeder is suggesting whatever.
Even with all your ducks lined up in a row, it still may be difficult to get bitch owners to take a chance on you and your untested stud (one that has not produced a litter).
