> I don't see the point in using any kind of milk or milk based food for weaning
I certainly agree that it isn't needed if the pups are older, but if your starting weaning very early because Mum has little milk it will be helpful.
Also most breeders start feeding pups so that the bitch doesn't bear such a strain as she would doing it all herself, and at that stage they still
need milk, we are helping Mum out so she doesn't loose condition.
I certainly like my pups to have milk until 6 weeks, and longer if they are tolerating it (certainly they do the goats milk based Nutrolac).
I have often found that once Mum closes the milk bar pups also are less tolerant of supplementary milk feeds (especially cows milk bassed formulations).
At the first signs of looseness I stop milk.
