Your question is a bit confusing. The puppies aren't even 3 weeks old, how and why would you even consider getting rid of them this early? They need to be kept together until they are at least 8 weeks old, no dog should leave it's litter before that time.
Never trust a tall dwarf... he's lying about something.
What breed is this? Have you taken them to the vet yet? They should have been wormed at 2 weeks, already. Why is the mother crying, is she locked in with the puppies? If so, let her out, they're just about old enough to start weaning, and you should be feeding the puppies, if you're not, already.Have you advertised them yet?
