I need your help

I don't know what to do anymore. Caesar gets very angry when he's tired or gets woken up. It used to be just at night but now it's in the morning. When I get up in the morning I go down stairs to let him outside for a pee and some play time before I go to work. Shane gets up for work before me. Caesar sleeps on the sofa so when I walk into the living I say "Good morning Caesar" to wake him up before I sit down beside him. This morning I said good morning and sat down. He woke up, stretched, I scratched his back (I just got fake nails, the animals love it!) then his lip started to twitch. I know what that means...he's getting angry. I would love to let him sleep in but he has to go for a pee before I leave for work. I continued talking to him in a soft voice and petting him but he kept getting madder and started growling. So I said "No growling" in a stern voice and tried to put my hand under him to lift him up. That's when he bit me, hard. I was even wearing my terry towel bathrobe and the bite left a terrible bruise. We don't want him biting. What if he bites Shane's son? It hurt me so I can only imagine what it would do to a child. How do I get him to stop biting and stop being so angry. I know I'm not the nicest person when I wake up but I've never tried to hurt someone for waking me. How do we correct this problem? When he does something bad, like steal DVDs and chew them, I stand over him and growl. I'm being the dominant one in the pack. After that he'll put his head down. He submits. But that technique doesn't work in this situation. What are we doing wrong? /forums/images/%%GRAEMLIN_URL%%/frown.gif Shane wants to get another dog but we can't bring another dog into our home while we have one with anger issues. How can we make him stop? I just don't know what to do.

This is the bite that I got this morning. (You can see Charlie on the BW calender in the background /forums/images/%%GRAEMLIN_URL%%/smile.gif )
