I really don't want to sound preachy or know-it-all, so I will just leave you with a story about an akita's prey drive.....
I have a male akita, he was raised and trained for both obedience and the conformation ring, he was housed with other dogs, he was around other dogs all the time...yet, at 9 months old he decided that HE was gonna be top dog...he attacked my older dog...we pulled him off. Put him through more training, etc. Did everything right...
Fast forward a few years. This male akita is never allowed out with any other dog now...there is no rehab great enough to overpower his intense dog aggression and prey drive. Unfortunately, a gate was left open. He attacked my younger male akita. He was going for the kill!!! The younger akita was crawling away from him, desperately trying to escape. There were two grown men and myself trying to break them up. We used anything we could find. My husband splintered a brand new wooden table chair across his back! He didn't even shudder!!!!! Finally, my one son went to get a gun. My husband couldn't bring himself to shoot the dog. He fired it into the air...finally Jigger walked away. It took over $700 to put Seger back together. Here is a dog that has been taught every command. He will listen immediately to any of them. However, when that prey drive kicks in, he is a totally different dog. He is that wolf that lurks in his ancestry and no one can stop him...until he is ready to stop. He knows "off", he knows "leave it", he knows "AAATTTT"...none of these work when they are 'set' on killing.
I am not trying to scare the OP away from her puppy. I am just trying to get her to understand the breed she is working with and that they are a totally different animal from a border collie or a setter...
