Feeding advise needed

So I got the 15 kg of burns sensitive duck and brown rice that I couldn't swap. It's only 18.5 crude protein and she get about 280gr daily. I mix it with nature diet for pupps that is 13% crude protein about 1/2 to 3/4 pack (395gr) daily and raw eggs, sardines, tuna, chicken ,hearts, liver cheese fruit and veg (everything..
. I plan to switch to raw that she loves when it's finished as she eats it happily when mixed. The problem is she's hungry all the time although she eats double the recomanded amount but there's not a gram fat on her she's slim and athletic and in good shape ( full of energy). Pups is 9.5 months now 17 kg on 17-+ inch.
Sorry for all the details but am I doing the right thing? As its not the food I would choose for her but its not bad either. I'm on my way to order 72 packs of nature diet puppy from berriewoods and was thinking to add frozen tripe and large bones. What are your thoughts?

Can't give advise on the raw side but I feed Moo what I feels she needs - I really do go on her condition rather than guidelines - if your happy go with it Xx

That's what I do Janey but maybe I'm missing something because she's hungry all the time I'm worried she's not getting what she needs .

They would all be hungry all the time given half a chance lol x

Yeah if she looks fit and well I wouldn't worry about feeding over guidelines   just make sure when your giving her anything raw don't feed any of the kibble for a few hours either side x

Loki was hungry on burns all the time!! So we switched him. If shes all well though and is just hungry she might be just seeing how much she can get ahah

Maybe u should switch the dog to all dry mix given half the chance mia would eat the shops stock lol

My Vin was like that as a pup, but we stuck to our guns and only gave him his daily allowance.

As already said, make sure you're not feeding raw and kibble together as it can cause tummy problems... always a few hours apart instead.

she looks great but can have up to 10kg more in time I don't want her overweight I just don't trust this burns kibble she eats it but it seems nutritionally empty for me the natures diet on the other side she wolfs in a sec unless frozen and needs 3-4 a day by itself .
I think ill just give it to charity and switch her to raw when she's off her season . Anybody knows good raw suppliers that will deliver to west-london? And where's good to buy green tripe? I used to buy from a local butcher but its ridicuilessly expensive over here and not too much choice . Tnx for help meanwhile we drown our sorrow in ice cream ...

Yeah I didnt like burns either, my trainer said that shes found alot of dogs dont put on weight very well, loki didnt like it that much,
