Feeding a Five Week Old Puppy

I don't know about the meat. I think it would be too harsh on the tummy.
When I have had young pups that the mother won't feed, we just warm a little milk, and let it soak into puppy chow food, then let the pup eat.

They will usually eat anything with milk on it as long as it is soft enough for them, until they get used to eating versus suckling. I would hold off on the meat for now. Good luck to you and your pup.
