I am totally uncomfortable with a rescue that adopts puppies out at such a young age.
In looking at their "website" I see that they are aligned with:
Rescue Alliance of Hairless & Other Breeds, Inc :: Home
That is apparently someone who has decided to represent independent rescuers...I don't have the time right now to totally look over their site, but it just seems that the way this is done, there is no one minding the store so to speak.
While these people who have these puppies may be well intentioned, I don't get releasing puppies at that age! I shudder to think what will happen to them later...we never release a pup until it is altered.
