If you were a responsible breeder, you would have homes lied up for them well ahead of time to not to worry about this.
95% of purebreds should be fixed (and ALL healthy mixes). Only purebred dogs who are two years old and up, have been titled, are ambassadors of their breed, and have passed through their genetic health screening with flying colours (a simple vet check doesn't cut it), should ever be bred. A new breeder should never attempt to breed if they do not have a mentor. Also, if you are serious about breeding; help out with rescue. A responsible breeder's knowledge of whelping comes in handy if there is ever a puppy mill bust, etc.
