Growling with the toy is perfectly normal. Growling at you to get away from his toy a little bit of an agressive behavior and you should try to curb it. If he's growling at you then get him to sit and take the toy away until he calms down. When he's older and play becomes more interative between you and Stuart, you can still teach him to sit and the 'drop it.' It turns your game of play into a learning and bonding experience for both of you.
Good luck with Stuart.
