Hi Annie,
If you search in the health topics there are lots of threads on what to feed for BARF. I've got two dogs, Bella has been on BARF since she was about 10 months and Zorro since 11 weeks, so this is what Zorro was fed as a pup:
Breakfast: 1 x chicken wing
Mid-morning: mince (I used the bags of frozen mince from Pets At Home as these have some bone content)
Mid-afternoon: mince or maybe scrambled egg
Evening: mince with some whizzed up veg
For amounts, I initially followed something I'd read which was to give them 10% of their bodyweight per day, so when Zorro weighed 4kg he was on 400g per day (a chicken wing is around 80-100g depending on size, then 3 lots of 100g of mince).
For the chicken wing, if she's never had one before you may want to bash it up to break up the bones for her and you may want to hold onto one end (can use pliers to make it a bit less grim) so that she learns not to guzzle it down in one go. They soon learn what to do though and you'll be amazed how those little puppy jaws can crunch up a boney little wing in no time at all.
Basically you want to feed the same kinds of food as you would to an adult dog but in different quantities, and while she's still on 4 meals I'd just stick initially to chicken wings and one type of mince, and then gradually start to introduce different types of meat. So you might start with the beef mince, and then introduce the rabbit, lamb, tripe etc but do it gradually.
I'd really recommend that you get a couple of the books recommended in other BARF threads so that you can find out more about what is needed, as although it doesn't have to be complicated, you do need to make sure that they get the correct balance of nutrients (enough offal-based foods, enough meat to bone ratio, omega oils etc etc). There are varying views on whether they need to have grains or vegetables and that seems to come down to individual choice, I know some COLers feed grains and some don't, but most of us seem to feed some veg.
Zorro is now 9 months old and has had impeccable health on this diet, his only trips to the vet have been for jabs and neutering, he's got a lovely glossy coat, bright eyes and absolutely bags of energy (pic of him here

On the behaviour front, I think if your dog is on a kibble that has lots of additives then you will probably notice a change if you switch to BARF, but it won't calm down loopy cocker puppy behaviour and Zorro is like a veritable Duracell bunny
. Good luck!
PS Raw bones are fine for them, especially soft chicken wing bones and breast of lamb, it's COOKED bones that you should never feed as they are splintery.
