If you mean to breed him to keep a puppy?
IN THEORY its as simple as finding a compliant bitch.
In reality its alot more complicated.
Mating is potentially dangerous all by itself. There is at least one canine STD for example, and it has the potential to mean that you'd have to put him down if he caught it. Also, even a bitch in fullblown fertile heat can be aggressive. Males have been severely injured by the bitch during attempted breedings.
Also pregnancy is potentially dangerous or fatal for the bitch, and if the mating was at your request you'd potentially be responsible for at least some of the medical costs.
Even if the mating and pregnancy goes smoothly its the rare breeding that only produces one pup. If the breeding was done at your request you're potentially partially responsible for finding homes for the rest of the pups and caring for them if new homes aren't forth-coming right away. Not to mention if the new homes don't work out, can you take back some or all of the pups and care for them till yet another new home is found?
And none of that is taking into account things like health testing (which is far more involved and costly than just having the vet announce him healthy and handsome), which really ought to be done on both the stud and bitch (and preferably their parents and grandparents) to help reduce the risk of them passing along a variety of health problems.
And personally as a puppy buyer I want to see more to recommend the parents than "he's sweet and healthy", some sort of proof of working or showing ability for example.
I would definetly recommend discussing it with his breeder, at least as a starting point.
