First, don't give your dog, puppy or adult, rawhide anything. It's not good for them if pieces are ingested. No, I'm not a vet but I've been told by several vets not to do this.
Second, it sounds like the dog has the impression she is the alpha in your relationship. Here's a trick I used with my new Brittany Spaniel and I've never had a problem out of her.
Have a package of crackers on the counter next to where you fix her food. When you're ready to give it to her, pick up one of the crackers and the bowl, get the dogs attention, and let her see you eat what she thinks is her food. The alpha always eats first in the canine world. I had my wife and even my two year old do this and now any of us, including my son, could walk up to her bowl while she's eating and she steps away. She does the same with her toys. She's not sacred, as none of us have ever hit her. She just knows we're the boss, not the other way around.
