If an owner had a top quality bitch of mine, but were not in a position to breed a litter themselves and I wanted a puppy for myself from her (say my line had come to an end or as is the case now I only have one breedable bitch and she may not produce what I want), then I would go with a
Loan of bitch agreement.
Actually I had a litter like this back in 2000, but it was other way around as the owners wanted a pup but were not in a position to breed.
The 'Loan of bitch agreement' was lodged with the Kennel club for a 12 month period to cover two seasons in case she missed. With such an agreement any litters would be mine.
I had the bitch to stay once confirmed in whelp, it was a huge responsibility, the bitch came to me with a digestive upset and refusing to eat. I had to hand feed her several times a day. She went into secondary inertia after first pup, ending in a C section. She had low calcium so had to supplement through rearing to prevent Eclampsia, while still hand feeding her 4 times a day as she was still not wanting to eat.
In the event they decided not to have a pup as the wife's health deteriorated.
I paid them the price of the puppy they were going to have for the loan of the bitch (much as you'd pay a stud fee for use of a dog), I absorbed all the costs, and sold the litter.
It was very stressful being responsible for someone else's bitch, as she could easily have died.
It was a worthwhile endeavour as one of the bitches was shown and bred from by her owners, though they never bred on into next generation. A male pup was sold to someone who started to show him as an adult and he became a champion. Sadly they never had him health tested, as they didn't want to have him used at stud.
