Hi, Paleo Twins, and interested others!

I saw all the great posts in response to your question, but I thought I
would add a point or two when dealing with dogbabies...

Four weeks is quite early to be weaned. Pups should ideally nurse another
two or even four weeks.  If that is not an option, they do need a little
extra care for the transition. Try a bit of ground beef on your finger.
They will usually suck or lick it off -if very young, which helps their
development. Watch your fingers, though- if they can't distinguish between
your finger and the meat, forget it, its too late for that. Puree up some
raw liver (beef or chicken) into a paste, and mix it with the ground beef
if they don't take it right away- although most puppies will. Raw eggs are
especially good. A bit of bone meal (raw ground) is good to make a paste
with eggs. Whole raw bones are fine, as long as they are small enough to
get their mouths around, but big enough not to swallow whole and choke on.
Chicken backs and wing are good for this.

If they are already taking and chewing bits of meat, they have graduated.
Just make sure they don't gulp down whole pieces. If they are, hold onto
one end, or give them a larger piece still attached to a bone to teach them
how to shred meat. Watch your fingers!

Have fun! The good news is that they will most likely bond really securely
to you, because at such a young age, their attachment to you will be strong
and never ending.
