Just had a look at your other post Sally and Dudleys is @ 10 wks - yes? If so he should be on four meals a day. If he is liking the raw tripe etc then IMHO he is telling you what he'd like to be fed
You can give him meals of rice pudding, scrambled egg, sardines in oil, tripe, lambs hearts - you can also give a natural holistic wholebake mixer.
My best bit of advice is to beg steal or borrow the book Give Your Dog A Bone by Dr Ian Billinghurst - he is the raw feeding guru and it explains everything you need to know about feeding your puppy.
Did Dudleys breeders not give you a puppy pack containing notes on exactly what he has had and how many times a day he's been getting fed
