Sounds about right, they don't call them land sharks for nothing. Shepherding breed puppies are going to bite, a lot, for quite awhile.
Personally, I do three things to deal with this. (AND AS ALWAYS THIS IS MY PERSONAL METHODS ONLY AND WOULD BE SUBJECT TO CHANGE DEPENDING ON THE DOG)
1. I work on redirecting with toys & play time. Teach her if she needs to bite something that's what her toys are for and if she's really wound up I'll typically work to calm her down, distract her, then take her outside to burn that energy off (a game of 2 ball with some training mixed in works very well for her). The three step process before going outside is to prevent her from learning that if she attacks me, then she gets to go play.
2. The command "gentle!" for when i don't have a toy handy. Teach her that gentle play and mouthing is different than hard bites and to be mindful of the sensitivity of human skin as she grows older and more powerful.
3. If she really bites me hard or unexpectedly I'll pop her bottom command her Nein! then ignore her till she asks for forgiveness. I'll then tell her it's okay, give her some love, and take her to go play. Again the three part process is important, she messed up & she got punished for it, but I'm accepting her apology and strengthening our bond.
ETA The third option is very rare as the first two are working very well, I'm blood free for a couple weeks now LOL
