Hi Diane
It is unusual to find a responsible breeder who will allow puppies to leave their dame before they are at least 8 weeks old - or at least that is what we found when we were looking for our pup.
Some puppy books recommend taking them from their litter mates and mother earlier than this, at about 6 weeks, as it is thought that the first 4 months are the most important time to socialise them with people and situations.
I think, although I am not sure, that our puppy, Molo, who we are picking up on Friday, was still drinking his dames milk at 6 weeks old, although he was also having four meals a day. He was also really tiny, and I'm not sure I would have been happy with such a fragile, tiny puppy at home without a lot more experience first :shock:
Some of the COL members are breeders; maybe they could advise you?
