I am so sorry to hear things didn't go as you had hoped. But i must agree with the other posters. The right baby will come along when the time is right! I too so long to add a baby right now, I know Ziggy would love that as he adores ather dogs! But I am trying to be patient and wait till I move out in about 8 months! And I know the right baby girl for our family will ome along at that time.
I believe that for you too. In the mean time, you could use this time to socialise your current puppy in preparation for your next baby
Good luck and please keep the faith
