Where does Malone sleep? If he sleeps in the bed with you, that can cause a huge problem with him asserting himself. It puts him on equal footing with you. Chester sleeps with me now, but he must ask for permission to get on the bed first.

How about food? Do you eat first? Or does he? Even if he eats 30 minutes before you, he still sees that he ate first, which means he's alpha to him.

Do you allow him on the furniture? If so, I would not allow that until you have this situation under control.

I strongly urge you not to swat him on the snout. He may very well react badly to that and become even more aggressive to you. You will achieve a lot more with positive reinforcement in the long run. It's a natural reaction if he does. It seems like Malone is asserting himself within his pack, not just being grouchy.

I really advise you to make him ask for everything he gets. I have found this to be the most effective method with Chester. And if anybody's ever had aggression issues, it's Chester.

And calling your trainer is the very best thing to do. Has Malone had any obedience training? If not, then get him in classes ASAP.
