I'm not going to persuade you either way Phillipa but there are some more scenario's to consider
How would you feel if you lost Saffi in whelp?
How would you feel if the puppies died at birth?
How would you feel if you lost some of the puppies after several days/weeks?
Can you be at home with them for at least 8/9 weeks & be with Saffi for at least 10 days before whelping?
What would happen if a new owner decided they didn't want their puppy after having them for several weeks/months?
What would happen if one of the owners came back to you after say 2 years for rehoming their dog?
How do you know you could 100% trust the stud dog/owner?....
some people will tell you what you want to hear but omit some facts e.g temperament/behaviour problems can skip a generation, whilst the stud dog may seem of sound temperament, his sire/dam may not be. There can also be other hereditatry health issues that are carried back in the stud dogs/dam line's that you don't know about.
Do you have a large bank balance?
seriously though you do need at least £2k just in case.
There are a couple of the above that have happened to us...firstly we sadly lost a 5 day old puppy.
This may not seem a huge issue to some people but after spending 5 sleepless nights trying to keep her alive & losing that battle it is totally heartbreaking.
Because i'm such a huge softy losing her affected me greatly & this is one reason i would never breed again. The second reason is because i put my trust into the stud dog owner but subsequently found out that the grandsire has similar behaviour issues to Nina (the puppy we kept).
We love Nina more than life itself BUT every day i thank god she stayed with us because i dread to think what would have happened to her in an inexperienced household.
Its not easy having a dog that is nervous, fearful & lacking in confidence.
None of the above crossed my mind before breeding & hindsight is a wonderful thing.
