Your girl is guarding what she thinks is hers. She's a puppy and has no idea what is acceptable behavior yet. What she is doing is normal.

I'm suprised you didn't find anything while searching. Try puppy biting, or resource guarding. This should net you a plethora of posts.

Leash her to you when you are outside or even in the house this way you can monitor where she is at and what she is doing. Keep a pocketful of treats and always carry a toy. When she picks up something she shouldn't have, which shouldn't happen as often if she is leashed to you, trade her for a treat. Give her a gentle tug of the leash, enough to get her attention. Remember she's only 10 weeks old so you don't have to yank. Say "no, leave it" . Make sure to praise her when she lets go of what she shouldn't have. If after she take the treat and starts biting at your hands redirect her to her toy.

Remember to be consistant on this. It takes awhile for pups to realize what is expected of them.
