hi! greeting from indonesia!

firstly, pardon for my bad english
i'm new chi owner, it's been 1 month already since we bought Alice.
she is 15 weeks now and really likes to bite anyone.
we can't pet her without being bitten.
she doesn't like to be held unless she want to sleep.
she also toe biter! sometimes she will growl while chasing people who walk.
i don't know whether that's play growl or aggresive growl though.
i already follow some suggestions to ignore her if she bite to hard, but if we ignore her, she will play with her toys. so i don't know if she really get what the ignore's means.
yelping loudly also doesn't work, she still bite.
i'm really scared she will be aggresive dog when she become adult later.
is it normal and will she outgrow it?
We have had dogs in the past but they didn't like to bite as often as alice, that's why i'm worried.
thanks before!
