I think that one important thing you need to bear in mind is the cost involved with having a litter for the bitches owner. As others have said without the relevent breed health tests in place and of good results you may well be left looking at using your lovely Lad on a not so good bitch. Owned by someone who has not got the breeding ethics you may look for if you were bying a pup.
The owner of the bitch may, like you just be thinking of having a litter in order to keep a pup "Like" hers. They may well not wish to spend money on expencive health tests and the costs of having a litter in time and energy not taking money into account are steep.
You would want to have a bitches owner fulfill all the points that YOU would look for in a good breeder if you were looking to go out and buy a new puppy, someone who would bring the pups up well, feed them properly, socialize them and keep them clean and happy. Someone who would make sure the pups went to great homes and not just sold to get them out of the house when at 5 weeks they become a real trial with poop and piddle everywhere and feeds 5 times a day.
What about the costs of an out of hours C-sect if this was needed? it could run into 100' of ££'s You would need to accept that as part of the deal you were responsible for helping with the costs. Feeding a bitch and pups is costly, what if she had just one pup born by C-sect and the bitches owner desided to keep it, you would be well out of pocket and with no pup. What if she had a lot of pups and new owners could not be found, would you accept responsibility for homing pups? Thinking to the future a good breeder would always re-home thier own pups if owners could not cope or had a change of circumstances....could or would you be prepared to do your share.
Puppies do not ask to be born in our society, we choose to breed them and so we need to accept full responsibility for them. We need to do them right from the day of conception through pregnancy, early weeks homing and keeping an eye on them for life. How would you feel if you later found out one of your boys babies was miss treated, became the centre of a cruelty case, bit a child badly or was left to wander the streets as a stray. All these things may seem unlikely but to many pups it is a fact of life.
Think long and hard about it. Better to source a great breeder who has similar lines to your boy, most of a dogs character is built by the owner (Though not all) and you would probably have the same traits in a new pup brought up in the same way even with an unrelated pup. The pup you kept may follow more in Mums character, or niether Mum or Dad, such is the way of breeding. I kept a pup from a litter I bred who was very antagonistic with her Mum to the point that we had to re-home her or live with our home seperated into different areas, I had another litter same Mother and kept a pup and she is 100% different in character and her and her Mum are great together.
There are no gaurentees in breeding.
