When Blue Rose Doxies weans their puppies, we use a different formula from the above paragraph.  This is what we do: 

We are adding bone dust to the mixture and some DE(Diatomaceous Earth).  It is the most wonderful thing.  It helps with wormings, parasites, fleas and more.  The puppies just love it.  We just put it down in a pie plate or a puppy dish, and let them go at it.  When they are through, we give the mother the remaining.
