Both of mine are fine about me messing with their food. Zack doesn't like Zoe anywhere near his precious chew bones, but he doesn't mind her near his bowl at all. It's nice not having to worry them being aggressive. Just the other day my nephew grabbed a bone right out of Zack's mouth, and Zack just looked at him like "uh, okay, I was going to chew on that, but nevermind"
