Good perspective everyone.
When I started feeding my pup raw about 4 months old, I would always make her sit and stay before chowing down. I would also pet her while eating and not once has she growled or acted aggressive over her food.
Now, at 6 months old I feel that she trusts me with anything. I can take her favorite beef bone/chicken drumstick right out of her mouth and she'll just happily tail whip me until I give it up, with no signs of aggression.
Now, if it's another dog trying to get close to her food, stay away.
