Good decision.
I would never breed from any of my dogs, as I wouldn't want to put them at risk - I also wouldn't be able to handle the responsibility of homing maybe 6 puppies for life to homes I thought were perfect. I would want to keep them all. You don't make any money from breeding if you do it properly, so that's not an incentive, in fact if things go wrong it could cost you an awful lot, as well as the risk of your bitch dying in whelp. No one talks about it, but it happens.
Far far better choice to go and find another puppy - but try and get one from a reputable breeder this time please
you should definitely see her mother at least, and visit a few times before you take her home. I am sure others will give you advice on how to find a good puppy - I personally have rescues nowadays - had you considered that ?
