Your Japanese chin may not have been as 'socialized' as you were told when you bought her. She may also need some time to get used to her surroundings and you. Japanese chins are normally VERY friendly dogs, especially at that age, if they are socialized properly before they go to a new home. Just give her some time.
Stealing toys is a puppy thing. They like to do that, so it's pretty normal. But the growling should just sound like a friendly-play growl, not one where she's being 'protective' about it.
