I think you did the right thing with your male that was for sale.... At 6 months of age he really needed to be in a forever home and get settled down where he is to live. If you felt the ones you sold him to were going to give him the home you desire for your puppies, then so be it. I don't know the time frame of the last time you had heard from the last client. If a couple of days had passed, I totally understand. But the others had contacted on the pup as well, so both clients had there chance. Now if you had promised the one client you would hold the pup until she had work out her financial problem that of course would have been another whole issue. And I didn't read anything to make me believe that was the case. So rest easy... you found a good home for you baby.
