I normally don't answer these kind of questions as I don't have a lot of experience, but I'll share my experience with food guarding.
I've only had Rafeal growl at me once. At the time he was still a bit unsure of trusting me to do the right thing by him and would have this "Do you need to fuss over me" personality. You yourself would know if Alodia seems to trust you to guide her in the right direction. I think it would help if you established your position more. I never fed him just because he howled, if I was busy he would have to wait a few minutes before I would feed him and I kept myself occupied by stoking him while he ate so it didn't seem like I was "waiting on him". I also hand fed him like you mentioned and then tried adding food to his bowl for him to get used to me. He is now very well behaved. One time the dog roll fell out of the fridge which he grabbed and I was able to take it off him without any trouble, not even a growl. He also will stop chewing or making a mess if I give him a certain tone of voice, no physical intervention is needed. Even a look is enough for him to stop himself from eating something that fell on the floor
Though I would never try to take his regular meals off him, I don't personally think that's something that should be done.
Hopefully someone has some better advice
