Agressive rescue dog

Question
I have a 12 pound poodle that we rescued from Katrina.  99% of the time he is delightful, however any time I lean over to pick him up, he turns his head away and looks at me out of the corner of his eyes, like he's not sure waht I'm going to do.  I talk to him, pet him before picking him up, etc. and usually have no problems.  

But on occasion, that 1%, he becomes an attack dog and it's very frightening.  I'm a vet tech and I've never personally owned a dog that I can't trust.  I'm not sure how much longer my husband and I can deal with him, and in good conscience I cannot give him to anyone else.  We have two other dogs, a 20# bichon male and a 7# bichon/poodle female.  All are neutered, however Dooley was not neutered when he arrived here in Iowa from Mississippi after the storm.  We estimate Dooley to be about 6 years old, and when he was found after the storm he was physically a mess, very long matted hair and obviously had not had much care before the storm.  He has never potty trained, in fact he wears 2-3T diapers when he's in the house.  I tried to house train him, but any quick moves or a raised voice as he lifts his leg, and he shakes and cowers.  He basically pees on everything vertical, inside or outside.  He's good about the diapers, waits at the door for us to remove them or put them back on, and we've made it a positive reinforcement time.  But I'd sure like to get rid of the expense!  He goes through an average of 2-3 diapers a day due to urinating in them.

Most recently he attacked both my husband and I on our bed.  My husband was leanig over to pick him up to put him in his doggie bed, and he bit my husband, myself and tried to get the other dogs.  He just becomes frantic and very agressive.  I am afraid to have grandkids around him, and even to have a house/dog sitter come during vacation time is scary.  I have to groom him myself, first knocking him almost totally out with Acepromazine, then doing his face quickly before putting on a muzzle.  As the Ace wears off, he'll lift up his head toward me like he wants to bite me.

Please help me, and help Dooley.  No, we don't exercise him enough, but I'm handicapped and can't really take him for walks.  Do I need to find a neighbor kid to do that for me?  The rest of the time he's very laid back, our Southern boy who just loves to snuggle next to one of us and spend the evening sleeping.  He has bitten us in several other situations, not just the bed, however he is banned from the bed now.

We have tried to apply Cesar's principles of being alpha over Dooley, and during this last attack my husband did grab a bath towel and was able to hold him down until he quit his frantic attacking and growling.

I know Dooley has some serious baggage, he's a survivor and I suspect has never had much kindness from humans.  But we adopted him two years ago this October, and I though by now he would be adjusted.  Please help us!  And most of all help Dooley, he's just not as happy as he could be.

Answer
The short answer is:
Put the damn dog down and stop picking it up! It is a direct descendent of a wolf and it's disrespectful and dangerous to pick it up. Jeez! Sit down if you want to hold it. Turning it's head away and looking out of the corner of the eye is an appeasement gesture. The dog is saying "Please oh please don't hurt me!" I haven't always wanted to figure out the equivalent of size monster that would be picking up a person. A scary giant for sure.

Every dog I get is treated like it is 7 weeks old and not potty trained. So that's right back to the basics in my handout. You can house train or you can put a dog in diapers you can't do both. I would choose toilet training. I might use a belly band instead of diapers to *prevent* him from peeing. Look it up under Tellington T Touch. (You can use an Ace bandage for the belly band)

Ace Promazine will make most any dog aggressive. Valium is a much better choice. (About 10 mg diazepam)

This is one scared dog and you people are making it worse. Why does he need to be picked up and put on his bed? he can get on it or not as he likes.

I think I would bite you people also and Cesar's methods do get most people hurt.

You need a professional who uses positive techniques only to come and do at least one session with you. You need to spend the money no matter what!
