I sold two puppies to a family in March... one was from my Lucy and the other was from my Wilma (they had litters 3 days apart).... I've heard from the family since then and they said that there was never any crying or anything because the two pups had each other. They were real happy they purchased the two together.
If you really want two... you might want to consider getting them together.
Best of luck with whatever you choose to do!
