Sadgirl,
He DID want you to pet him when he came to you...the point is HE is telling you to pet him when he does that, and HE is not supposed to be making any decisions right now, you are. My dogs do it all the time, and yes, I pet them...but they don't have any issues with exactly who is "alpha". Read up on Nothing in Life is Free (NILIF)....in that you'll learn that the dog must EARN affection..that's why I told you in an earlier post to have him do something (like a "sit")..then you can reward him for that by petting him...he's just earning it, not demanding it.
I still think leashing him to you might be good...it really helps with the bonding and helps establish who is "boss". You can even hook it through a belt loop and keep both hands free...then just go about doing whatever you normally do in the house and he has to follow you.
I'm also wondering if hubby needs to keep "hands off" for a while, ignore Moose, and let you be the one to interact with Moose until he has a chance to bond to you...you feed him, you interact with him. Although I don't think this is the case, sometimes the person the dog is strongly attached to actually reinforces bad behavior by the dog to the other person (strokes their ego's)...but even if hubby's not doing that, I still think all the attention Moose gets should only be from you right now.
I'm also wondering if you could keep a bag of treats (TINY bits of hot dog, cheese..something the dog loves) handy and whenever he comes over to you, you could simply say "good boy" and drop one.
I wish someone more versed in behavior modification would chime in...but my feelings are this...he's growling when you approach him because he's uncomfortable (for whatever reason)...maybe he's even guarding (guarding hubby, guarding the dog bed..whatever)...if you push the point, then you are convincing him that he really DOES need to guard (or be uncomfortable). I might even try tossing him a treat and walking off...I'm thinking that might alter his perception of your approach being a scary thing to "oh, boy..here she comes"....they do this when teaching dogs to be non-reactive to other approaching dogs...dog sees other dog, starts to react, gets treats...soon it's "WOW...here comes another dog...oh, boy where are my treats!!!"
I just think
1. you need to keep everything positive with him right now, and
2. demonstrate his place in the pack structure (ie, the bottom!!) by doing NILIF.
