My dog growled at me.... :(?

My husky growls at me all the time. When he's chewing on his rawhide and I "play" take it off of him, or when I grab him and tackle him and play with him, but he would NEVER growl in an aggressive manner. Maybe he was just play growling. If not, and this continues, then he might be getting what's called food aggression. To solve this, start by taking his food and hand feeding him pieces, putting your hands in the dish while he's eating, taking the rawhide off of him, pretending to chew on it (I know it sounds ridiculous) and giving it back to him. All these little things will show him that you want to share his food, and you're not going to take it from him.
