Rue is food possessive

Little grubber really likes her eats, and anything to do with real meat seems to make her primal roots come out to the forefront.  Considering we hope to get her on a raw diet eventually, I wonder if this is more of a concern?
 
She growls if touched while eating from her bowl, and when presented with high-value chewies like real beef jerky or a pig ear, she really wants to grab and run.  When I held it and let her chew, I was seeing a lot of white eye as she stared up at me, and she was really trying to goose swallow the thing.  It wasn't relaxed at all.  Baked ears and lamb ears don't do this to her, and neither to bully sticks.  Kibble isn't a huge interest to her, but when additives like yogurt, fruit, cottage cheese etc are added to it, or if meat is involved in any way, growling and wanting to grab and run begin.
 
I'm not super worried: puppy class starts next week and this seems to be reserved for specific foods right now so is avoidable for the time being.  I do want to make sure this doesn't continue to get worse though.

which we're going to start ASAP, because it's not so cute even in a 10 week old puppy to be told off.  It's amazing how though how my parent's initial reaction to the growling upon being touched is to keep touching her deliberately!?  Why!?  To make the point that you can?  Gah!!  Any thoughts?  I've never actually had to deal with this problem before.
