Hiya,
Cant help with the quantities im afraid, my experience of raising a pup on a raw diet was wiht a lurcher pup who is at a year old considerable smaller than your Akita pup will be......
As far as mixing complete food with raw, id advise not to. Id personally advise a totally raw diet, but thats just me. If you do wish to feed complete, do NOT mix the two foods together. Processed dried or wet food will be digested by your dog much much faster than raw....if the bulk of teh stomach contents are complete food, when thats digested, everything goes through, so if you are mixing say, raw minced beef for example, with a dried food, the raw stuff will not be fully digested.
Feed the different foods at different meals, to avoid that happening.
Someone else will help with the amounts of food to feed im sure.
