@bulldogburger Karen gave some great advice. If you know an approximate weight that he will grow to be using his parents' weight, then feed approximately 2 to 3% of that to your pup. You should feed FOUR times a day (no matter what you feed, even kibble) at this age. Around 4 months you can drop to 3 times, at 6 months drop to two, and 1 year you can take him down to one meal a day. If you start feeding and notice the dog looks like it might be losing a bit of weight, DONT PANIC, just up the food a bit. It will take time to figure out how to feed. My Gypsy (7 months now!) lost a bit so I moved her portion up to 3% of her projected adult weight instead of 2%.
Bone means bone. Chicken bones are the best as they are soft and already in his food. Also, chicken seems to be the easiest for them to get used to while they are adjusting unless he has already been on raw from the breeder, then ask the breeder for some advice and what his current diet is. BE SURE TO MAKE SURE THE CHICKEN IS NOT ENHANCED! Meaning, that it has not been injected with broth, etc. An easy way to tell is look at the sodium content on the package. If it more than 100mg it is probably enhanced and might give him some tummy troubles. As Annie said, you can do wings, breasts, and legs for a pup of that size. If you notice his poops are runny, then add a little more bone, if they are too hard or he gets constipated, then take some bone out and feed more meat. You should keep the pieces larger at first so that he will need to gnaw and chew it. It will help satisfy that puppy chewing urge too

. Never give any cooked bones. They can splinter and they are choking hazards. Raw bones are softer and safe. Also, never feed bones from the large animals such as beef, elk, moose, deer, etc. After a few weeks you can add in organs, starting with liver...just a sliver...at any rate, I will PM you a great group where you can research to your heart's content and ask questions. You can ask questions here as well as everyone here that raw feeds is fantastic! The other up side is once you know what to buy and can introduce more things, you can hit all of the good sales and "manager's specials" at the store and it may end up being cheaper than kibble in the long run.
Good luck!
