I have a litter of 5 week old pups (mod edit giant breed). They are on beta puppy for large breed which I soak, but I am contemplating adding some minced tripe. Is this too young? Any views or experiences greatly appreciated.

No problem, have fed to 4 week old medium breed puppies.

Flatocats ...dinner plates of raw minced tripe , chopped up boiled eggs scattered over the top and a sprinkle of bone meal ...yummy.
