Hi there, first off to consider is do you have breeding rights to your dog
most reputable breeders require you to sign a contract that states they are sold as pets, and must be spayed
you are under contract in most cases and the dog can be taken back and you could be sued
2ndly,,have you done testing on your female
3rd are you willing to stand behind every single pup you sell?
there is way more to breeding then just throwing two dogs together, and hoping for the best ,,its alot of responsiblity , to the pups you produce and the families that adopt from you
