Haha ... barking already at 8.5 weeks
You got yourself a little firecracker

This one has a real sense of herself
and she's likely getting used to the new household
and might be missing her siblings ..... you chasing after her and holding her in place is probably scaring her
and you might do better with trying to entice her into play rather than picking her up and making her play

This way she will see sooner that interaction with humans is a good thaing rather than something to be afraid of

With a puppy this headstrong it's best to start treat training sooner rather than later

But barking and biting should never be tolerated
NO! .... and she gets left alone
