Mooshi,

I just wanted to say, that I use a Breeder, who will not let one of his Females become pregnant, UNLESS he has a sufficient number of customers, for the Dogs to be placed. (and no exceptions)
We had to wait for about 3 months, to get our Female Becca.

I think this should be the only way one could get another Dog.
If you're not willing to wait, then, you probably didn't need one anyway

I admit the wait was grueling. We already had all the toys, bunks and stuff for a new puppy, from getting Sneakers, so, we didn't have anything to do, just twiddle our thumbs in anticipation !

Have a good Day !
S.W.
