When Star was Gracie's age, she was very protective of her food too - and ravenous! As she grew up, her food protecting lessened, she got to the point she'd leave her food alone for days. Actually, it was having another dog there that got her to eat more regularly.
I don't know about pigs ears (gave Star one once, she buried it)
but I don't let my dogs have rawhide anything because they WILL fight over itl
Huskies are wonderful dogs...yeah, they may be a bit more work than some breeds, but I think it's worth it! Hang in there with Gracie.
